The domestic dog (Canis lupus familiaris when considered a subspecies of the wolf or Canis familiaris when considered a distinct species) is a member of the genus Canis (canines), which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The dog and the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated, which implies that the direct ancestor of the dog is extinct. The dog was the first species to be domesticated and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes.
Their long association with humans has led dogs to be uniquely attuned to human behavior and they are able to thrive on a starch-rich diet that would be inadequate for other canid species. Dogs vary widely in shape, size and colors. They perform many roles for humans, such as hunting, herding, pulling loads, protection, assisting police and military, companionship and, more recently, aiding disabled people and therapeutic roles. This influence on human society has given them the sobriquet of "man's best friend".

In 1999, a study of mitochondrial DNA indicated that the domestic dog may have originated from multiple grey wolf populations, with the dingo and New Guinea singing dog "breeds" having developed at a time when human populations were more isolated from each other. In the third edition of Mammal Species of the World published in 2005, the mammalogist W. Christopher Wozencraft listed under the wolf Canis lupus its wild subspecies, and proposed two additional subspecies: "familiaris Linneaus, 1758 [domestic dog]" and "dingo Meyer, 1793 [domestic dog]". Wozencraft included hallstromi – the New Guinea singing dog – as a taxonomic synonym for the dingo. Wozencraft referred to the mDNA study as one of the guides in forming his decision. The inclusion of familiaris and dingo under a "domestic dog" clade has been noted by other mammalogists. This classification by Wozencraft is debated among zoologists.
The origin of the domestic dog is not clear. It is known that the dog was the first domesticated species. The domestic dog is a member of the genus Canis (canines), which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The closest living relative of the dog is the gray wolf and there is no evidence of any other canine contributing to its genetic lineage. The dog and the extant gray wolf form two sister clades, with modern wolves not closely related to the wolves that were first domesticated. The archaeological record shows the first undisputed dog remains buried beside humans 14,700 years ago, with disputed remains occurring 36,000 years ago. These dates imply that the earliest dogs arose in the time of human hunter-gatherers and not at the dawn of agriculture.
Where the genetic divergence of dog and wolf took place remains controversial, with the most plausible proposals spanning Western Europe, Central Asia, and East Asia. This has been made more complicated by the most recent proposal that fits the available evidence, which is that an initial wolf population split into East and West Eurasian wolves, these were then domesticated independently before going extinct into two distinct dog populations between 14,000-6,400 years ago, and then the Western Eurasian dog population was partially and gradually replaced by East Asian dogs that were brought by humans at least 6,400 years ago.
Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes. Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal. Dogs are predators and scavengers, and like many other predatory mammals, the dog has powerful muscles, fused wrist bones, a cardiovascular system that supports both sprinting and endurance, and teeth for catching and tearing.
Dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier, that stood only 6.3 cm (2.5 in) at the shoulder, 9.5 cm (3.7 in) in length along the head-and-body, and weighed only 113 grams (4.0 oz). The largest known dog was an English Mastiff which weighed 155.6 kg (343 lb) and was 250 cm (98 in) from the snout to the tail. The tallest dog is a Great Dane that stands 106.7 cm (42.0 in) at the shoulder.
The dog's senses include vision, hearing, sense of smell, sense of taste, touch and sensitivity to the earth's magnetic field. Another study suggested that dogs can see the earth's magnetic field.
The coats of domestic dogs are of two varieties: "double" being common with dogs (as well as wolves) originating from colder climates, made up of a coarse guard hair and a soft down hair, or "single", with the topcoat only.
Domestic dogs often display the remnants of countershading, a common natural camouflage pattern. A countershaded animal will have dark coloring on its upper surfaces and light coloring below, which reduces its general visibility. Thus, many breeds will have an occasional "blaze", stripe, or "star" of white fur on their chest or underside.
Regarding coat appearance or health, the coat can be maintained or affected by multiple nutrients present in the diet, see Coat (dog) for more information.
There are many different shapes for dog tails: straight, straight up, sickle, curled, or cork-screw. As with many canids, one of the primary functions of a dog's tail is to communicate their emotional state, which can be important in getting along with others. In some hunting dogs, however, the tail is traditionally docked to avoid injuries. In some breeds, such as the Braque du Bourbonnais, puppies can be born with a short tail or no tail at all.
Despite their close genetic relationship and the ability to inter-breed, there are a number of diagnostic features to distinguish the gray wolves from domestic dogs. Domesticated dogs are clearly distinguishable from wolves by starch gel electrophoresis of red blood cell acid phosphatase. The tympanic bullae are large, convex and almost spherical in gray wolves, while the bullae of dogs are smaller, compressed and slightly crumpled. Compared with equally sized wolves, dogs tend to have 20% smaller skulls and 30% smaller brains.:35 The teeth of gray wolves are also proportionately larger than those of dogs. Dogs have a more domed forehead and a distinctive "stop" between forehead and nose. The temporalis muscle that closes the jaws is more robust in wolves.:p158 Wolves do not have dewclaws on their back legs, unless there has been admixture with dogs that had them. Most dogs lack a functioning pre-caudal gland and enter estrus twice yearly, unlike gray wolves which only do so once a year. So-called primitive dogs such as dingoes and Basenjis retain the yearly estrus cycle.
Dogs generally have brown eyes and wolves almost always have amber or light colored eyes. The skin of domestic dogs tends to be thicker than that of wolves, with some Inuit tribes favoring the former for use as clothing due to its greater resistance to wear and tear in harsh weather. The paws of a dog are half the size of those of a wolf, and their tails tend to curl upwards, another trait not found in wolves. The dog has developed into hundreds of varied breeds, and shows more behavioral and morphological variation than any other land mammal. For example, height measured to the withers ranges from a 6 inches (150 mm) in the chihuahua to 3.3 feet (1.0 m) in the Irish wolfhound; color varies from white through grays (usually called "blue") to black, and browns from light (tan) to dark ("red" or "chocolate") in a wide variation of patterns; coats can be short or long, coarse-haired to wool-like, straight, curly, or smooth. It is common for most breeds to shed their coat.
Some breeds of dogs are prone to certain genetic ailments such as elbow and hip dysplasia, blindness, deafness, pulmonic stenosis, cleft palate, and trick knees. Two serious medical conditions particularly affecting dogs are pyometra, affecting unspayed females of all types and ages, and gastric dilatation volvulus (bloat), which affects the larger breeds or deep-chested dogs. Both of these are acute conditions, and can kill rapidly. Dogs are also susceptible to parasites such as fleas, ticks, mites, hookworms, tapeworms, roundworms, and heartworms (roundworm species that lives in the heart of dogs), keeps it from beating properly, and will eventually lead to death.
A number of common human foods and household ingestibles are toxic to dogs, including chocolate solids (theobromine poisoning), onion and garlic (thiosulphate, sulfoxide or disulfide poisoning), grapes and raisins, macadamia nuts, xylitol, as well as various plants and other potentially ingested materials. The nicotine in tobacco can also be dangerous. Dogs can be exposed to the substance by scavenging garbage or ashtrays; eating cigars and cigarettes. Signs can be vomiting of large amounts (e.g., from eating cigar butts) or diarrhea. Some other signs are abdominal pain, loss of coordination, collapse, or death. Dogs are susceptible to theobromine poisoning, typically from ingestion of chocolate. Theobromine is toxic to dogs because, although the dog's metabolism is capable of breaking down the chemical, the process is so slow that for some dogs even small amounts of chocolate can be fatal, especially dark chocolate.
In 2013, a study found that mixed breeds live on average 1.2 years longer than pure breeds, and that increasing body-weight was negatively correlated with longevity (i.e. the heavier the dog the shorter its lifespan).
The typical lifespan of dogs varies widely among breeds, but for most the median longevity, the age at which half the dogs in a population have died and half are still alive, ranges from 10 to 13 years. Individual dogs may live well beyond the median of their breed.
The breed with the shortest lifespan (among breeds for which there is a questionnaire survey with a reasonable sample size) is the dogue de Bordeaux, with a median longevity of about 5.2 years, but several breeds, including miniature bull terriers, bloodhounds, and Irish wolfhounds are nearly as short-lived, with median longevities of 6 to 7 years.
The longest-lived breeds, including toy poodles, Japanese spitz, Border terriers, and Tibetan spaniels, have median longevities of 14 to 15 years. The median longevity of mixed-breed dogs, taken as an average of all sizes, is one or more years longer than that of purebred dogs when all breeds are averaged. The longest-lived dog was "Bluey", who died in 1939 at age 29.5 years of age.
In domestic dogs, sexual maturity begins to happen around age six to twelve months for both males and females, although this can be delayed until up to two years old for some large breeds. This is the time at which female dogs will have their first estrous cycle. They will experience subsequent estrous cycles semiannually, during which the body prepares for pregnancy. At the peak of the cycle, females will come into estrus, being mentally and physically receptive to copulation. Because the ova survive and are capable of being fertilized for a week after ovulation, it is possible for more than one male to sire the same litter.
Dogs bear their litters roughly 58 to 68 days after fertilization, with an average of 63 days, although the length of gestation can vary. An average litter consists of about six puppies, though this number may vary widely based on the breed of dog. In general, toy dogs produce from one to four puppies in each litter, while much larger breeds may average as many as twelve.
Some dog breeds have acquired traits through selective breeding that interfere with reproduction. Male French Bulldogs, for instance, are incapable of mounting the female. For many dogs of this breed, the female must be artificially inseminated in order to reproduce.
Neutering refers to the sterilization of animals, usually by removal of the male's testicles or the female's ovaries and uterus, in order to eliminate the ability to procreate and reduce sex drive. Because of the overpopulation of dogs in some countries, many animal control agencies, such as the American Society for the Prevention of Cruelty to Animals (ASPCA), advise that dogs not intended for further breeding should be neutered, so that they do not have undesired puppies that may later be euthanized.
According to the Humane Society of the United States, 3–4 million dogs and cats are euthanized each year in the United States and many more are confined to cages in shelters because there are many more animals than there are homes. Spaying or castrating dogs helps keep overpopulation down. Local humane societies, SPCAs, and other animal protection organizations urge people to neuter their pets and to adopt animals from shelters instead of purchasing them.
Neutering reduces problems caused by hypersexuality, especially in male dogs. Spayed female dogs are less likely to develop some forms of cancer, affecting mammary glands, ovaries, and other reproductive organs. However, neutering increases the risk of urinary incontinence in female dogs, and prostate cancer in males, as well as osteosarcoma, hemangiosarcoma, cruciate ligament rupture, obesity, and diabetes mellitus in either sex.
A common breeding practice for pet dogs is mating between close relatives (e.g. between half- and full siblings). Inbreeding depression is considered to be due largely to the expression of homozygous deleterious recessive mutations. Outcrossing between unrelated individuals, including dogs of different breeds, results in the beneficial masking of deleterious recessive mutations in progeny.
In a study of seven breeds of dogs (Bernese mountain dog, basset hound, Cairn terrier, Epagneul Breton, German Shepherd dog, Leonberger, and West Highland white terrier) it was found that inbreeding decreases litter size and survival. Another analysis of data on 42,855 dachshund litters found that as the inbreeding coefficient increased, litter size decreased and the percentage of stillborn puppies increased, thus indicating inbreeding depression. In a study of boxer litters, 22% of puppies died before reaching 7 weeks of age. Stillbirth was the most frequent cause of death, followed by infection. Mortality due to infection increased significantly with increases in inbreeding.
Dog intelligence is the ability of the dog to perceive information and retain it as knowledge for applying to solve problems. Dogs have been shown to learn by inference. A study with Rico showed that he knew the labels of over 200 different items. He inferred the names of novel items by exclusion learning and correctly retrieved those novel items immediately and also 4 weeks after the initial exposure. Dogs have advanced memory skills. A study documented the learning and memory capabilities of a border collie, "Chaser", who had learned the names and could associate by verbal command over 1,000 words. Dogs are able to read and react appropriately to human body language such as gesturing and pointing, and to understand human voice commands, although a 2018 study on canine cognitive abilities found that dogs' capabilities are not more exceptional than those of other animals, such as horses, chimpanzees or cats.
Dogs demonstrate a theory of mind by engaging in deception. An experimental study showed compelling evidence that Australian dingos can outperform domestic dogs in non-social problem-solving, indicating that domestic dogs may have lost much of their original problem-solving abilities once they joined humans. Another study indicated that after undergoing training to solve a simple manipulation task, dogs that are faced with an insoluble version of the same problem look at the human, while socialized wolves do not. Modern domestic dogs use humans to solve their problems for them.
Dog behavior is the internally coordinated responses (actions or inactions) of the domestic dog (individuals or groups) to internal and/or external stimuli. As the oldest domesticated species, with estimates ranging from 9,000–30,000 years BCE, the minds of dogs inevitably have been shaped by millennia of contact with humans. As a result of this physical and social evolution, dogs, more than any other species, have acquired the ability to understand and communicate with humans, and they are uniquely attuned to human behaviors. Behavioral scientists have uncovered a surprising set of social-cognitive abilities in the domestic dog. These abilities are not possessed by the dog's closest canine relatives nor by other highly intelligent mammals such as great apes but rather parallel some of the social-cognitive skills of human children.
Unlike other domestic species which were primarily selected for production-related traits, dogs were initially selected for their behaviors. In 2016, a study found that there were only 11 fixed genes that showed variation between wolves and dogs. These gene variations were unlikely to have been the result of natural evolution, and indicate selection on both morphology and behavior during dog domestication. These genes have been shown to affect the catecholamine synthesis pathway, with the majority of the genes affecting the fight-or-flight response (i.e. selection for tameness), and emotional processing. Dogs generally show reduced fear and aggression compared with wolves. Some of these genes have been associated with aggression in some dog breeds, indicating their importance in both the initial domestication and then later in breed formation. Traits of high sociability and lack of fear in dogs may include genetic modifications related to Williams-Beuren syndrome in humans, which cause hypersociability at the expense of problem solving ability.
Dog communication is about how dogs convey information to other dogs, how they understand messages from humans, and how humans translate the information that dogs are transmitting.:xii Communication behaviors of dogs include eye gaze, facial expression, vocalization, body posture (including movements of bodies and limbs) and gustatory communication (scents, pheromones and taste). Humans communicate to dogs by using vocalization, hand signals and body posture.
In 2013, an estimate of the global dog population was 987 million. Although it is said that the "dog is man's best friend", this refers largely to the ~20% of dogs that live in developed countries. In the developing world dogs are more commonly feral, or village or community dogs, with pet dogs uncommon. Most of these dogs live their lives as scavengers and have never been owned by humans, with one study showing their most common response when approached by strangers is to run away (52%) or respond aggressively (11%). Little is known about these dogs, or the dogs in developed countries that are feral, stray or are in shelters, because the great majority of modern research on dog cognition has focused on pet dogs living in human homes.
Although dogs are most abundant and widely distributed terrestrial carnivores, the potential of feral and free-ranging dogs to compete with other large carnivores is limited by their strong association with humans. For example, a review of the studies in the competitive effects of dogs on sympatric carnivores did not mention any research on competition between dogs and wolves. Although wolves are known to kill dogs, they tend to live in pairs or in small packs in areas where they are highly persecuted, giving them a disadvantage facing large dog groups.
Wolves kill dogs wherever they are found together. One study reported that in Wisconsin in 1999 more compensation had been paid for losses due to wolves taking dogs than for wolves taking livestock. In Wisconsin wolves will often kill hunting dogs, perhaps because they are in the wolf's territory. A strategy has been reported from Russia where one wolf lures a dog into heavy brush where the another animal waits in ambush. In some instances, wolves have displayed an uncharacteristic fearlessness of humans and buildings when attacking dogs, to the extent that they have to be beaten off or killed. Although the numbers of dogs killed each year are relatively low, it induces a fear of wolves entering villages and farmyards to take dogs, and losses of dogs to wolves has led to demands for more liberal wolf hunting regulations.
Coyotes and big cats have also been known to attack dogs. Leopards in particular are known to have a predilection for dogs, and have been recorded to kill and consume them regardless of their size. Tigers in Manchuria, Indochina, Indonesia, and Malaysia are also reported to kill dogs. Striped hyenas are known to kill dogs in Turkmenistan, India, and the Caucasus.
Dogs have been described as carnivores or omnivores. Compared to wolves, dogs have genes involved in starch digestion that contribute to an increased ability to thrive on a starch-rich diet. Based on metabolism and nutrition, many consider the dog to be an omnivore. However, the dog is not simply an omnivore. More like the cat and less like the other omnivores, the dog can only produces bile acid with taurine and it cannot produce vitamin D, which it obtains from animal flesh. Also more like the cat, the dog requires argenine to maintain its nitrogen balance. These nutritional requirements place the dog part-way between the carnivores and the omnivores.
As a domesticated or semi-domesticated animal, the dog is nearly universal among human societies. Notable exceptions once included:
The domestic dog is the first species, and the only large carnivore, known to have been domesticated. Especially over the past 200 years, dogs have undergone rapid phenotypic change and were formed into today's modern dog breeds due to artificial selection by humans. These breeds can vary in size and weight from a 0.46 kg (1.0 lb) teacup poodle to a 90 kg (200 lb) giant mastiff. Phenotypic variation can include height measured to the withers ranging from 15.2 centimetres (6.0 in) in the Chihuahua to 76 cm (30 in) in the Irish Wolfhound; color varies from white through grays (usually called "blue") to black, and browns from light (tan) to dark ("red" or "chocolate") in a wide variation of patterns; coats can be short or long, coarse-haired to wool-like, straight, curly, or smooth. The skull, body, and limb proportions vary significantly between breeds, with dogs displaying more phenotypic diversity than can be found within the entire order of carnivores. Some breeds demonstrate outstanding skills in herding, retrieving, scent detection, and guarding, which demonstrates the functional and behavioral diversity of dogs. The first dogs were domesticated from shared ancestors of modern wolves, however the phenotypic changes that coincided with the dog–wolf genetic divergence are not known.
Domestic dogs inherited complex behaviors, such as bite inhibition, from their wolf ancestors, which would have been pack hunters with complex body language. These sophisticated forms of social cognition and communication may account for their trainability, playfulness, and ability to fit into human households and social situations, and these attributes have given dogs a relationship with humans that has enabled them to become one of the most successful species on the planet today.:pages95-136
The dogs' value to early human hunter-gatherers led to them quickly becoming ubiquitous across world cultures. Dogs perform many roles for people, such as hunting, herding, pulling loads, protection, assisting police and military, companionship, and, more recently, aiding handicapped individuals. This influence on human society has given them the nickname "man's best friend" in the Western world. In some cultures, however, dogs are also a source of meat.
Wolves, and their dog descendants, likely derived significant benefits from living in human camps – more safety, more reliable food, lesser caloric needs, and more chance to breed. They would have benefited from humans' upright gait that gives them larger range over which to see potential predators and prey, as well as better color vision that, at least by day, gives humans better visual discrimination. Camp dogs would also have benefited from human tool use, as in bringing down larger prey and controlling fire for a range of purposes.
Humans would also have derived enormous benefit from the dogs associated with their camps. For instance, dogs would have improved sanitation by cleaning up food scraps. Dogs may have provided warmth, as referred to in the Australian Aboriginal expression "three dog night" (an exceptionally cold night), and they would have alerted the camp to the presence of predators or strangers, using their acute hearing to provide an early warning.
It has been suggested that the most significant benefit would have been the use of dogs' robust sense of smell to assist with the hunt. The relationship between the presence of a dog and success in the hunt is often mentioned as a primary reason for the domestication of the wolf, and a 2004 study of hunter groups with and without a dog gives quantitative support to the hypothesis that the benefits of cooperative hunting was an important factor in wolf domestication.
The cohabitation of dogs and humans likely improved the chances of survival for early human groups, and the domestication of dogs may have been one of the key forces that led to human success.
Human emigrants from Siberia that came across the Bering land bridge into North America likely had dogs in their company. Although one writer even suggests that the use of sled dogs may have been critical to the success of the waves that entered North America roughly 12,000 years ago, the earliest archaeological evidence of dog-like canids in North America dates from about 9,400 years ago.:104 Dogs were an important part of life for the Athabascan population in North America, and were their only domesticated animal. Dogs as pack animals may have contributed migration of the Apache and Navajo tribes 1,400 years ago. This use of dogs in these cultures often persisted after the introduction of the horse to North America.
It is estimated that three-quarters of the world's dog population lives in the developing world as feral, village, or community dogs, with pet dogs uncommon.
"The most widespread form of interspecies bonding occurs between humans and dogs" and the keeping of dogs as companions, particularly by elites, has a long history. (As a possible example, at the Natufian culture site of Ain Mallaha in Israel, dated to 12,000 BC, the remains of an elderly human and a four-to-five-month-old puppy were found buried together). However, pet dog populations grew significantly after World War II as suburbanization increased. In the 1950s and 1960s, dogs were kept outside more often than they tend to be today (using the expression "in the doghouse" to describe exclusion from the group signifies the distance between the doghouse and the home) and were still primarily functional, acting as a guard, children's playmate, or walking companion. From the 1980s, there have been changes in the role of the pet dog, such as the increased role of dogs in the emotional support of their human guardians. People and dogs have become increasingly integrated and implicated in each other's lives, to the point where pet dogs actively shape the way a family and home are experienced.
There have been two major trends in the changing status of pet dogs. The first has been the 'commodification' of the dog, shaping it to conform to human expectations of personality and behaviour. The second has been the broadening of the concept of the family and the home to include dogs-as-dogs within everyday routines and practices.
There are a vast range of commodity forms available to transform a pet dog into an ideal companion. The list of goods, services and places available is enormous: from dog perfumes, couture, furniture and housing, to dog groomers, therapists, trainers and caretakers, dog cafes, spas, parks and beaches, and dog hotels, airlines and cemeteries. While dog training as an organized activity can be traced back to the 18th century, in the last decades of the 20th century it became a high-profile issue as many normal dog behaviors such as barking, jumping up, digging, rolling in dung, fighting, and urine marking (which dogs do to establish territory through scent), became increasingly incompatible with the new role of a pet dog. Dog training books, classes and television programs proliferated as the process of commodifying the pet dog continued.
The majority of contemporary dog owners describe their pet as part of the family, although some ambivalence about the relationship is evident in the popular reconceptualization of the dog–human family as a pack. A dominance model of dog–human relationships has been promoted by some dog trainers, such as on the television program Dog Whisperer. However it has been disputed that "trying to achieve status" is characteristic of dog–human interactions. Pet dogs play an active role in family life; for example, a study of conversations in dog–human families showed how family members use the dog as a resource, talking to the dog, or talking through the dog, to mediate their interactions with each other.
Increasingly, human family members are engaging in activities centered on the perceived needs and interests of the dog, or in which the dog is an integral partner, such as dog dancing and dog yoga.
According to statistics published by the American Pet Products Manufacturers Association in the National Pet Owner Survey in 2009–2010, it is estimated there are 77.5 million people with pet dogs in the United States. The same survey shows nearly 40% of American households own at least one dog, of which 67% own just one dog, 25% two dogs and nearly 9% more than two dogs. There does not seem to be any gender preference among dogs as pets, as the statistical data reveal an equal number of female and male dog pets. Yet, although several programs are ongoing to promote pet adoption, less than a fifth of the owned dogs come from a shelter.
The latest study using magnetic resonance imaging (MRI) comparing humans and dogs showed that dogs have the same response to voices and use the same parts of the brain as humans do. This gives dogs the ability to recognize emotional human sounds, making them friendly social pets to humans.
Dogs have lived and worked with humans in many roles. In addition to dogs' role as companion animals, dogs have been bred for herding livestock (collies, sheepdogs), hunting (hounds, pointers), and rodent control (terriers). Other types of working dogs include search and rescue dogs, detection dogs trained to detect illicit drugs or chemical weapons; guard dogs; dogs who assist fishermen with the use of nets; and dogs that pull loads. In 1957, the dog Laika became the first animal to be launched into Earth orbit, aboard the Soviets' Sputnik 2; she died during the flight.
Various kinds of service dogs and assistance dogs, including guide dogs, hearing dogs, mobility assistance dogs, and psychiatric service dogs provide assistance to individuals with disabilities. Some dogs owned by epileptics have been shown to alert their handler when the handler shows signs of an impending seizure, sometimes well in advance of onset, allowing the guardian to seek safety, medication, or medical care.
In conformation shows, also referred to as breed shows, a judge familiar with the specific dog breed evaluates individual purebred dogs for conformity with their established breed type as described in the breed standard. As the breed standard only deals with the externally observable qualities of the dog (such as appearance, movement, and temperament), separately tested qualities (such as ability or health) are not part of the judging in conformation shows.
Dog meat is consumed in some East Asian countries, including Korea, China and Vietnam, a practice that dates back to antiquity. It is estimated that 13–16 million dogs are killed and consumed in Asia every year. In China, debates have ensued over banning the consumption of dog meat. Other cultures, such as Polynesia and pre-Columbian Mexico, also consumed dog meat in their history. However, Western, South Asian, African, and Middle Eastern cultures, in general, regard consumption of dog meat as taboo. In some places, however, such as in rural areas of Poland, dog fat is believed to have medicinal properties – being good for the lungs for instance. Dog meat is also consumed in some parts of Switzerland. Proponents of eating dog meat have argued that placing a distinction between livestock and dogs is western hypocrisy, and that there is no difference with eating the meat of different animals.
The most popular Korean dog dish is gaejang-guk (also called bosintang), a spicy stew meant to balance the body's heat during the summer months. Followers of the custom claim this is done to ensure good health by balancing one's gi, or vital energy of the body. A 19th century version of gaejang-guk explains that the dish is prepared by boiling dog meat with scallions and chili powder. Variations of the dish contain chicken and bamboo shoots. While the dishes are still popular in Korea with a segment of the population, dog is not as widely consumed as beef, chicken, and pork.
Citing a 2008 study, the U.S. Center for Disease Control estimated in 2015 that 4.5 million people in the USA are bitten by dogs each year. A 2015 study estimated that 1.8% of the U.S. population is bitten each year. In the 1980s and 1990s the US averaged 17 fatalities per year, while since 2007 this has increased to an average of 31. 77% of dog bites are from the pet of family or friends, and 50% of attacks occur on the property of the dog's legal owner.
A Colorado study found bites in children were less severe than bites in adults. The incidence of dog bites in the US is 12.9 per 10,000 inhabitants, but for boys aged 5 to 9, the incidence rate is 60.7 per 10,000. Moreover, children have a much higher chance to be bitten in the face or neck. Sharp claws with powerful muscles behind them can lacerate flesh in a scratch that can lead to serious infections.
In the United States, cats and dogs are a factor in more than 86,000 falls each year. It has been estimated around 2% of dog-related injuries treated in UK hospitals are domestic accidents. The same study found that while dog involvement in road traffic accidents was difficult to quantify, dog-associated road accidents involving injury more commonly involved two-wheeled vehicles.
Toxocara canis (dog roundworm) eggs in dog feces can cause toxocariasis. In the United States, about 10,000 cases of Toxocara infection are reported in humans each year, and almost 14% of the U.S. population is infected. In Great Britain, 24% of soil samples taken from public parks contained T. canis eggs. Untreated toxocariasis can cause retinal damage and decreased vision. Dog feces can also contain hookworms that cause cutaneous larva migrans in humans.
The scientific evidence is mixed as to whether companionship of a dog can enhance human physical health and psychological wellbeing. Studies suggesting that there are benefits to physical health and psychological wellbeing have been criticised for being poorly controlled, and finding that "[t]he health of elderly people is related to their health habits and social supports but not to their ownership of, or attachment to, a companion animal." Earlier studies have shown that people who keep pet dogs or cats exhibit better mental and physical health than those who do not, making fewer visits to the doctor and being less likely to be on medication than non-guardians.
A 2005 paper states "recent research has failed to support earlier findings that pet ownership is associated with a reduced risk of cardiovascular disease, a reduced use of general practitioner services, or any psychological or physical benefits on health for community dwelling older people. Research has, however, pointed to significantly less absenteeism from school through sickness among children who live with pets." In one study, new guardians reported a highly significant reduction in minor health problems during the first month following pet acquisition, and this effect was sustained in those with dogs through to the end of the study.
In addition, people with pet dogs took considerably more physical exercise than those with cats and those without pets. The results provide evidence that keeping pets may have positive effects on human health and behaviour, and that for guardians of dogs these effects are relatively long-term. Pet guardianship has also been associated with increased coronary artery disease survival, with human guardians being significantly less likely to die within one year of an acute myocardial infarction than those who did not own dogs.
The health benefits of dogs can result from contact with dogs in general, and not solely from having dogs as pets. For example, when in the presence of a pet dog, people show reductions in cardiovascular, behavioral, and psychological indicators of anxiety. Other health benefits are gained from exposure to immune-stimulating microorganisms, which, according to the hygiene hypothesis, can protect against allergies and autoimmune diseases. The benefits of contact with a dog also include social support, as dogs are able to not only provide companionship and social support themselves, but also to act as facilitators of social interactions between humans. One study indicated that wheelchair users experience more positive social interactions with strangers when they are accompanied by a dog than when they are not. In 2015, a study found that pet owners were significantly more likely to get to know people in their neighborhood than non-pet owners.
The practice of using dogs and other animals as a part of therapy dates back to the late 18th century, when animals were introduced into mental institutions to help socialize patients with mental disorders. Animal-assisted intervention research has shown that animal-assisted therapy with a dog can increase social behaviors, such as smiling and laughing, among people with Alzheimer's disease. One study demonstrated that children with ADHD and conduct disorders who participated in an education program with dogs and other animals showed increased attendance, increased knowledge and skill objectives, and decreased antisocial and violent behavior compared with those who were not in an animal-assisted program.
Every year, between 6 and 8 million dogs and cats enter US animal shelters. The Humane Society of the United States (HSUS) estimates that approximately 3 to 4 million of those dogs and cats are euthanized yearly in the United States. However, the percentage of dogs in US animal shelters that are eventually adopted and removed from the shelters by their new legal owners has increased since the mid-1990s from around 25% to a 2012 average of 40% among reporting shelters (with many shelters reporting 60–75%).
Dogs have been viewed and represented in different manners by different cultures and religions, over the course of history.
In ancient Mesopotamia, from the Old Babylonian period until the Neo-Babylonian, dogs were the symbol of Ninisina, the goddess of healing and medicine, and her worshippers frequently dedicated small models of seated dogs to her. In the Neo-Assyrian and Neo-Babylonian periods, dogs were used as emblems of magical protection.
In mythology, dogs often serve as pets or as watchdogs. Stories of dogs guarding the gates of the underworld recur throughout Indo-European mythologies and may originate from Proto-Indo-European religion. In Greek mythology, Cerberus is a three-headed watchdog who guards the gates of Hades. In Norse mythology, a bloody, four-eyed dog called Garmr guards Helheim. In Persian mythology, two four-eyed dogs guard the Chinvat Bridge. In Welsh mythology, Annwn is guarded by Cŵn Annwn. In Hindu mythology, Yama, the god of death, owns two watch dogs who have four eyes. They are said to watch over the gates of Naraka.
The hunter god Muthappan from North Malabar region of Kerala has a hunting dog as his mount. Dogs are found in and out of the Muthappan Temple and offerings at the shrine take the form of bronze dog figurines. In Philippine mythology, Kimat who is the pet of Tadaklan, god of thunder, is responsible for lightning. The role of the dog in Chinese mythology includes a position as one of the twelve animals which cyclically represent years (the zodiacal dog).
In Christianity, dogs represent faithfulness. Within the Roman Catholic denomination specifically, the iconography of Saint Dominic includes a dog, after the hallow's mother dreamt of a dog springing from her womb and becoming pregnant shortly thereafter. As such, the Dominican Order (Ecclesiastical Latin: Dominicanus) means "dogs of the Lord" of "hounds of the Lord" (Ecclesiastical Latin: domini canis). In Christian folklore, a church grim often takes the form of a black dog to guard Christian churches and their churchyards from sacrilege.
Jewish law does not prohibit keeping dogs and other pets. Jewish law requires Jews to feed dogs (and other animals that they own) before themselves, and make arrangements for feeding them before obtaining them.
The view on dogs in Islam is mixed, with some schools of thought viewing it as unclean, although Khaled Abou El Fadl states that this view is based on "pre-Islamic Arab mythology" and "a tradition to be falsely attributed to the Prophet". Therefore, Sunni Malaki and Hanafi jurists permit the trade of and keeping of dogs as pets.
Cultural depictions of dogs in art extend back thousands of years to when dogs were portrayed on the walls of caves. Representations of dogs became more elaborate as individual breeds evolved and the relationships between human and canine developed. Hunting scenes were popular in the Middle Ages and the Renaissance. Dogs were depicted to symbolize guidance, protection, loyalty, fidelity, faithfulness, watchfulness, and love.
The American Kennel Club reopened a museum called "Museum of the Dog" in Manhattan after moving the attraction from outside of St. Louis. The museum contains ancient artifacts, fine art, and educational opportunities for visitors.
Although the cause of pet overpopulation is multifaceted, the lack of guardians choosing to spay or neuter their animals is a major contributing factor.
The African wild dog (Lycaon pictus), also known as the painted hunting dog, painted wolf, African hunting dog, Cape hunting dog or African painted dog, is a canid native to sub-Saharan Africa. It is the largest of its family in Africa, and the only extant member of the genus Lycaon, which is distinguished from Canis by dentition highly specialised for a hypercarnivorous diet, and a lack of dewclaws. It was classified as endangered by the IUCN in 2016, as it had disappeared from much of its original range. The 2016 population was estimated at roughly 39 subpopulations containing 6,600 adults, only 1,400 of which were reproductive. The decline of these populations is ongoing, due to habitat fragmentation, human persecution and disease outbreaks.The African wild dog is a highly social animal, living in packs with separate dominance hierarchies for males and females. Uniquely among social carnivores, the females rather than the males scatter from the natal pack once sexually mature and the young are allowed to feed first on carcasses. The species is a specialised diurnal hunter of antelopes, which it catches by chasing them to exhaustion. Like other canids, it regurgitates food for its young, but this action is also extended to adults, to the point of being the bedrock of African wild dog social life. It has few natural predators, though lions are a major source of mortality and spotted hyenas are frequent kleptoparasites.
Although not as prominent in African folklore or culture as other African carnivores, it has been respected in several hunter-gatherer societies, particularly those of the predynastic Egyptians and the San people.Bulldog
The Bulldog, also known as the British Bulldog or English Bulldog, is a medium-sized breed of dog. It is a muscular, hefty dog with a wrinkled face and a distinctive pushed-in nose. The American Kennel Club (AKC), The Kennel Club (UK), and the United Kennel Club (UKC) oversee breeding records. Bulldogs were the fourth most popular purebreed in the US in 2016 according to the American Kennel Club.Bulldogs have a longstanding association with English culture, as the BBC wrote: "to many the Bulldog is a national icon, symbolising pluck and determination." During World War II, Bulldogs were often likened to Prime Minister Winston Churchill and his defiance of Nazi Germany. When the English settled in the Americas, their Bulldogs came with them. A few dedicated bulldog fanciers formed the Bulldog Club of America in 1890 and it was incorporated under the laws of the State of New York on November 29, 1904.Chihuahua (dog)
The Chihuahua (listen) (Spanish: chihuahueño) is the smallest breed of dog and is named after the state of Chihuahua in Mexico. Chihuahuas come in a wide variety of colors, and two coat lengths.Dachshund
The dachshund (UK: /ˈdakshʊnd/ or US: DAHKS-huunt or ) (English: badger dog; also known as the sausage dog or wiener dog) is a short-legged, long-bodied, hound-type dog breed.
The standard size dachshund was developed to scent, chase, and flush out badgers and other burrow-dwelling animals, while the miniature dachshund was bred to hunt smaller prey such as rabbits. In the United States, they have also been used to track wounded deer and hunt prairie dogs.
Dachshunds also participate in conformation shows, field trials and many other events organized through pure-bred dog organizations such as the American Kennel Club (AKC). According to the AKC, the dachshund is ranked in 13th place in popularity amongst dog breeds in the United States.Feces
Feces (or faeces) are the solid or semisolid remains of the food that could not be digested in the small intestine. Bacteria in the large intestine further break down the material. Feces contain a relatively small amount of metabolic waste products such as bacterially altered bilirubin, and the dead epithelial cells from the lining of the gut.Feces are discharged through the anus or cloaca during a process called defecation.
Feces can be used as fertilizer or soil conditioner in agriculture. It can also be burned and used as a fuel source or dried and used as a construction material. Some medicinal uses have been found. In the case of human feces, fecal transplants or fecal bacteriotherapy are in use. Urine and feces together are called excreta.German Shepherd
The German Shepherd (German: Deutscher Schäferhund, German pronunciation: [ˈʃɛːfɐˌhʊnt]) is a breed of medium to large-sized working dog that originated in Germany. In the English language, the breed's officially recognized name is German Shepherd Dog (sometimes abbreviated as GSD). The breed was officially known as the Alsatian in Britain until 1977 when its name was changed back to German Shepherd. The German Shepherd is a relatively new breed of dog, with their origin dating to 1899. As part of the Herding Group, German Shepherds are working dogs developed originally for herding sheep. Since that time however, because of their strength, intelligence, trainability, and obedience, German Shepherds around the world are often the preferred breed for many types of work, including disability assistance, search-and-rescue, police and military roles, and acting. The German Shepherd is the second-most registered breed by the American Kennel Club and seventh-most registered breed by The Kennel Club in the United Kingdom.Golden Retriever
The Golden Retriever is a large-sized breed of dog bred as gun dogs to retrieve shot waterfowl, such as ducks and upland game birds, during hunting and shooting parties, and were named 'retriever' because of their ability to retrieve shot game undamaged (soft mouth). Golden retrievers have an instinctive love of water, and are easy to train to basic or advanced obedience standards. They are a long-coated breed, with a dense inner coat that provides them with adequate warmth in the outdoors, and an outer coat that lies flat against their bodies and repels water. Golden retrievers are well suited to residency in suburban or country environments. They shed copiously, particularly at the change of seasons, and require fairly regular grooming. The Golden Retriever was originally bred in Scotland in the mid-19th century.The breed is a prominent participant in conformation shows for purebred dogs. The Golden Retriever is popular as a disability assistance dog, such as being a guide dog for the blind and a hearing dog for the deaf. In addition, they are trained to be a hunting dog, a detection dog, and a search and rescue participant. The breed's friendly, gentle temperament means it is unsuited to being a professional guard dog, but its temperament has also made it the third-most popular family dog breed (by registration) in the United States,
the fifth-most popular in Brazil and Australia,
and the eighth-most popular in the United Kingdom. Golden Retrievers are rarely choosy eaters, but require ample (two or more hours a day) exercise. The breed is fond of play but also highly trainable.Hot dog
The hot dog or dog (also spelled hotdog) is a grilled or steamed link-sausage sandwich where the sausage is served in the slit of a partially sliced hot dog bun, a bun of size and shape to hold the sausage. It can also refer to the sausage (the wurst or wörst) of its composition itself. The sausage used is the wiener (Vienna sausage) or frankfurter (also frank). The names of these sausages also commonly refer to their assembled sandwiches. Typical condiments include mustard, ketchup, mayonnaise, and relish, and common garnishes include onions, sauerkraut, chili, cheese, coleslaw, and olives. Hot dog variants include the corn dog and pigs in a blanket. The hot dog's cultural traditions include the Nathan's Hot Dog Eating Contest and the Oscar Mayer Wienermobile.
These types of sausages and their sandwiches were culturally imported from Germany and became popular in the United States, where the "hot dog" became a working-class street food sold at hot dog stands and carts. The hot dog became closely associated with baseball and American culture. Hot dog preparation and condiments vary regionally in the US. Although particularly connected with New York City and its cuisine, the hot dog eventually became ubiquitous throughout the US during the 20th century, and emerged as an important part of other regional cuisines, including notably Chicago street cuisine.Labrador Retriever
The Labrador Retriever, or just Labrador, is a large type of retriever-gun dog. The Labrador is one of the most popular breeds of dog in Canada, the United Kingdom and the United States.A favourite disability assistance breed in many countries, Labradors are frequently trained to aid the blind, those who have autism, to act as a therapy dog, or to perform screening and detection work for law enforcement and other official agencies. Additionally, they are prized as sporting and hunting dogs.A few kennels breeding their ancestors, the St. John's water dog, were in England. At the same time, a combination of the sheep protection policy in Newfoundland and the rabies quarantine in the United Kingdom led to the gradual demise of the St. John's water dog in Canada.In the 1830s, the 10th Earl of Home and his nephews the 5th Duke of Buccleuch and Lord John Scott, had imported progenitors of the breed from Newfoundland to Europe for use as gundogs. Another early advocate of these Newfoundland dogs, or Labrador Retrievers as they later became known, was the 2nd Earl of Malmesbury who bred them for their expertise in waterfowling.During the 1880s, the 3rd Earl of Malmesbury, the 6th Duke of Buccleuch and the 12th Earl of Home collaborated to develop and establish the modern Labrador breed. The dogs Buccleuch Avon and Buccleuch Ned, given by Malmesbury to Buccleuch, were mated with female dogs carrying blood from those originally imported by the 5th Duke and the 10th Earl of Home. The offspring are considered to be the ancestors of modern Labradors.List of dog breeds
Dogs have been selectively bred for thousands of years, sometimes by inbreeding dogs from the same ancestral lines, while at other times by mixing dogs from very different lines. The process continues today, resulting in a widening in appearance without speciation, "from the Chihuahua to the Great Dane".The following list uses a wide interpretation of the word "breed". Breeds are usually categorized by the functional type from which the breed was developed. The basic types are companion dogs, guard dogs, hunting dogs, herding dogs and working dogs, although there are many other types and subtypes. Breeds listed here may be traditional breeds with long histories as registered breeds, rare breeds with their own registries, or new breeds that may still be under development.
In some cases, a breed's origin overlaps the boundaries of two or more countries; the dog is normally listed only in the country with which it is most commonly associated; for example, by its designated country according to the Fédération Cynologique Internationale (FCI). Some dogs, such as the Löwchen, have an uncertain origin and are thus listed under several countries.Pit bull
Pit bull is the common name for a type of dog descended from bulldogs and terriers. The pit bull type is particularly ambiguous as it encompasses a range of pedigree breeds, informal types and appearances that cannot be reliably identified. Formal breeds often considered to be of the pit bull type include the American Pit Bull Terrier, American Staffordshire Terrier, American Bully, and Staffordshire Bull Terrier. The American Bulldog is also sometimes included. Mixed-breed dogs which physically resemble these breeds often get labelled as "pit bulls" by shelters. Many of these breeds were originally developed as fighting dogs from cross breeding bull-baiting dogs (used to hold the faces and heads of larger animals such as bulls) and terriers. After the use of dogs in blood sports was banned, such dogs were used as catch dogs in the United States for semi-wild cattle and hogs, to hunt and drive livestock, and as family companions. Despite dog fighting now being illegal in the United States, it still exists as an underground activity, and pit bulls are a common type used.Owners of pit bull-type dogs deal with a strong breed stigma, however controlled studies have not identified this breed group as disproportionately dangerous. Because owners of stigmatized breeds are more likely to have involvement in criminal and/or violent acts, breed correlations may have the owner's behavior as the underlying causal factor. Some jurisdictions have enacted legislation banning the group of breeds, and some insurance companies do not cover liability from pit bull bites. Among other roles, pit bulls have served as police dogs, search and rescue dogs, and several have appeared on film.Pomeranian (dog)
The Pomeranian (often known as a Pom) is a breed of dog of the Spitz type that is named for the Pomerania region in north-west Poland and north-east Germany in Central Europe. Classed as a toy dog breed because of its small size, the Pomeranian is descended from the larger Spitz-type dogs, specifically the German Spitz. It has been determined by the Fédération Cynologique Internationale to be part of the German Spitz breed; and in many countries, they are known as the Zwergspitz ("Dwarf-Spitz").
The breed has been made popular by a number of royal owners since the 18th century. Queen Victoria owned a particularly small Pomeranian and consequently, the smaller variety became universally popular. During Queen Victoria's lifetime alone, the size of the breed had decreased by half. Overall, the Pomeranian is a sturdy, healthy dog. The most common health issues are luxating patella and tracheal collapse. More rarely, the breed can have Alopecia X, a skin condition colloquially known as "black skin disease". This is a genetic disease which causes the dog's skin to turn black and lose all or most of its hair. As of 2013, in terms of registration figures, since at least 1998, the breed has ranked among the top fifty most popular breeds in the US, and the current fashion for small dogs has increased their popularity worldwide.Poodle
Poodles are a group of formal dog breeds, the Standard Poodle, Miniature Poodle and Toy Poodle. The origin of the breed is still discussed, with a prominent dispute over whether the poodle descends from Germany as a type of water dog, or from the French Barbet.Ranked second most intelligent dog breed just behind the Border Collie, the poodle is skillful in many dog sports and activities, including agility, obedience, tracking to herding, circus performers and assistance dogs. Poodles have taken top honors in many conformation shows, including "Best in Show" at the Westminster Kennel Club Dog Show in 1991 and 2002, and at the World Dog Show in 2007 and 2010.
Toy Poodles won "Best in Show" at Crufts in 1966 and 1982. Standard Poodles achieved the award in 1955, 1985, 2002, and 2014. The 2002 winner came from Norway and was the first overseas exhibit to win the Crufts best in show award.Prairie dog
Prairie dogs (genus Cynomys) are herbivorous burrowing rodents native to the grasslands of North America. The five species are: black-tailed, white-tailed, Gunnison's, Utah, and Mexican prairie dogs. They are a type of ground squirrel, found in the United States, Canada and Mexico. In Mexico, prairie dogs are found primarily in the northern states, which lie at the southern end of the Great Plains: northeastern Sonora, north and northeastern Chihuahua, northern Coahuila, northern Nuevo León, and northern Tamaulipas. In the United States, they range primarily to the west of the Mississippi River, though they have also been introduced in a few eastern locales. Despite the name, they are not actually canines.Pug
The pug is a breed of dog with physically distinctive features of a wrinkly, short-muzzled face, and curled tail. The breed has a fine, glossy coat that comes in a variety of colours, most often fawn or black, and a compact square body with well-developed muscles.
Pugs were brought from China to Europe in the sixteenth century and were popularized in Western Europe by the House of Orange of the Netherlands, and the House of Stuart. In the United Kingdom, in the nineteenth century, Queen Victoria developed a passion for pugs which she passed on to other members of the Royal family.
Pugs are known for being sociable and gentle companion dogs. The American Kennel Club describes the breed's personality as "even-tempered and charming". Pugs remain popular into the twenty-first century, with some famous celebrity owners. A pug was judged Best in Show at the World Dog Show in 2004.Shiba Inu
The Shiba Inu (柴犬, Japanese: [ɕiba̠ inɯ̟ᵝ]) is the smallest of the six original and distinct spitz breeds of dog native to Japan.A small, agile dog that copes very well with mountainous terrain, the Shiba Inu was originally bred for hunting. It looks similar to and is often mistaken for other Japanese dog breeds like the Akita Inu or Hokkaido, but the Shiba Inu is a different breed with a distinct blood line, temperament and smaller size than other Japanese dog breeds.Shih Tzu
A Shih Tzu (UK: , US: ; Chinese: 西施犬; pinyin: Xī Shī quǎn, literally "Xi Shi dog"), also known as the Chrysanthemum Dog, is a toy dog breed, weighing from 4 to 7.25 kilograms (9–16 lbs) when fully grown. The breed developed in China. The exact origin is unknown and is thought to have originated in the Tibetan Plateau.Siberian Husky
The Siberian Husky (Russian: Сибирский хаски, lit: Sibirskiy Haski) is a medium size working dog breed that originated in Northeast Asia. The breed belongs to the Spitz genetic family. With proper training, they make great sled dogs. It is recognizable by its thickly furred double coat, erect triangular ears, and distinctive markings, and is smaller than a very similar-looking dog, the Alaskan Malamute.
The original Siberian Huskies were bred by the Chukchi people — whose hunter-gatherer culture relied on their help. It is an active, energetic, resilient breed, whose ancestors lived in the extremely cold and harsh environment of the Siberian Arctic. William Goosak, a Russian fur trader, introduced them to Nome, Alaska during the Nome Gold Rush, initially as sled dogs. The people of Nome referred to Siberian Huskies as "Siberian Rats" due to their size of 40–50 lb (18–23 kg), versus the Malamutes size of 75–85 lb (34–39 kg).Snoop Dogg
Calvin Cordozar Broadus Jr. (born October 20, 1971), known professionally as Snoop Dogg, is an American rapper, singer, record producer, television personality, entrepreneur, and actor. His music career began in 1992 when he was discovered by Dr. Dre and featured on Dre's solo debut, "Deep Cover", and then on Dre's solo debut album, The Chronic. He has since sold over 23 million albums in the United States and 35 million albums worldwide.Snoop's debut album, Doggystyle, produced by Dr. Dre, was released in 1993 by Death Row Records. Bolstered by excitement driven by Snoop's featuring on The Chronic, the album debuted at number one on both the Billboard 200 and Billboard Top R&B/Hip-Hop Albums charts. Selling almost a million copies in the first week of its release, Doggystyle became certified quadruple platinum in 1994 and spawned several hit singles, including "What's My Name?" and "Gin & Juice". In 1994 Snoop released a soundtrack on Death Row Records for the short film Murder Was the Case, starring himself. His second album, Tha Doggfather (1996), also debuted at number one on both charts, with "Snoop's Upside Ya Head" as the lead single. The album was certified double platinum in 1997.
After leaving Death Row Records, Snoop signed with No Limit Records, where he recorded his next three albums, Da Game Is to Be Sold, Not to Be Told (1998), No Limit Top Dogg (1999), and Tha Last Meal (2000).
