Canis familiaris Linnaeus ,  . 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.
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. This influence on human society has given them the sobriquet of " man's best friend ". In , the Swedish botanist and zoologist Carl Linnaeus published in his Systema Naturae the binomial nomenclature — or the two-word naming — of species.
Canis is the Latin word meaning "dog",  and under this genus he listed the dog-like carnivores including domestic dogs, wolves, and jackals. He classified the domestic dog as Canis familiaris , and on the next page he classified the wolf as Canis lupus. In , 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.
Christopher Wozencraft listed under the wolf Canis lupus its wild subspecies, and proposed two additional subspecies: " familiaris Linneaus, [domestic dog]" and " dingo Meyer, [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 origin of the domestic dog includes the dog's evolutionary divergence from the wolf, its domestication , and its development into dog types and dog breeds.
The dog is a member of the genus Canis , which forms part of the wolf-like canids , and was the first species and the only large carnivore to have been domesticated. The genetic divergence between dogs and wolves occurred between 40,—20, years ago, just before or during the Last Glacial Maximum.
Where the domestication of the dog took place remains debated, with the most plausible proposals spanning Western Europe ,   Central Asia   and East Asia. These two groups, before going extinct , were domesticated independently into two distinct dog populations between 14, and 6, years ago. The Western Eurasian dog population was gradually and partially replaced by East Asian dogs introduced by humans at least 6, years ago. Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes.
Dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier , that stood only 6. The largest known dog was an English Mastiff which weighed 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.
Breeds may 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. Premature graying can occur in dogs from as early as one year of age.
This has been shown to be associated with impulsive behaviors , anxiety behaviors , fear of noise, and fear of unfamiliar people or animals. 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. 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. Dogs generally have brown eyes and wolves almost always have amber or light colored eyes. There are many household plants that are poisonous to dogs and other mammals including begonia , Poinsettia and aloe vera.
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.
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. Dogs can be exposed to the substance by scavenging through garbage bins or ashtrays and eating cigars and cigarettes.
Signs can be vomiting of large amounts e. Some other signs are abdominal pain, loss of coordination, collapse, or death.
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. Dogs are also vulnerable to some of the same health conditions as humans, including diabetes , dental and heart disease, epilepsy, cancer, hypothyroidism, and arthritis.
In , a study found that mixed breeds live on average 1. 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. 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.
The longest-lived breeds, including toy poodles , Japanese spitz , Border terriers , and Tibetan spaniels , have median longevities of 14 to 15 years. In domestic dogs, sexual maturity happens around six to twelve months of age 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. Fertilization typically occurs 2—5 days after ovulation; 14—16 days after ovulation, the embryo attaches to the uterus, and after more days the heart beat is detectable. 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.
Spaying or castrating dogs helps keep overpopulation down. Neutering reduces problems caused by hypersexuality , especially in male dogs. A common breeding practice for pet dogs is mating between close relatives e. 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.
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 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, 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 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.
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. 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.
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.
Dog communication is how dogs convey information to other dogs, how they understand messages from humans, and how humans translate the information that dogs are transmitting. Humans communicate to dogs by using vocalization, hand signals and body posture. In , an estimate of the global dog population was million. In the developing world, dogs are more commonly feral or communally owned, with pet dogs uncommon.
Although dogs are the 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. Wolves kill dogs wherever they are found together. In Wisconsin wolves will often kill hunting dogs, possibly because the dogs are in the wolf's territory. 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.
Dogs have been described as carnivores   or omnivores. However, the dog is not simply an omnivore. More like the cat and less like other omnivores, the dog can only produce bile acid with taurine , and it cannot produce vitamin D , which it obtains from animal flesh. Also more like the cat, the dog requires arginine to maintain its nitrogen balance.
These nutritional requirements place the dog part-way between carnivores and omnivores. As a domesticated or semi-domesticated animal, the dog is nearly universal among human societies. Notable exceptions once included:. Dogs were introduced to Antarctica as sled dogs , and some became nearly feral. Dogs became apex predators in Antarctica by killing prey largely penguins and posing a risk of spreading contagious diseases to seals before dogs were outlawed in Antarctica in accordance with an international agreement.
