The wolf on the right has a broad snout and large nose pad, with small ears relative to its head size. Distinguishing dogs from wolves can be challenging. Many of the traits possessed by wolves can also be found in domestic dogs, so no single trait should be used to definitively distinguish a dog from a wolf. Wild wolves will almost never approach a human. It can be impossible to distinguish a large dog from a wolf from a single track. Instead, if possible look for the pattern of the trail left by the animal.
Wolves canis lupus , coyotes canis latrans , and domestic dogs canis familiaris are closely-related species. All three can interbreed and produce viable, fertile offspring — wolfdogs, coywolves, and coydogs. Through DNA analysis, scientists have established that the wolf is the ancestor of the dog. Dogs and wolves are so closely related that DNA analysis cannot distinguish a wolf from a dog or a wolfdog hybrid.
Coyotes, however can be distinguished from wolves and dogs through DNA analysis. Scientists can identify a coywolf from a coyote and a wolf, and a coydog from a coyote and a dog. The red wolf canis niger has been shown to be a coyote-wolf hybrid. Wolves, coyotes and dogs are social creatures. Wolves form extended family groups consisting of the male and female, their young, and juveniles from the previous year's litter. They have a complex social hierarchy that allows for cooperative living, hunting, and defense of territory with minimal social stress, and still maintains temperament differences among individual pack members.
Coyotes had long been thought to be loners, living on their own except during breeding season. Recent research in Yellowstone National Park and elsewhere, however, has shown that coyotes, where they are not hunted by man, live in social groups like wolves.
However, their feet are relatively smaller than the rest of the body. The body length of an averagely-built coyote is about 76 — 86 centimetres and the height at the withers is about 58 — 66 centimetres. They stay as large groups and hunt in pairs.
These territorial animals are primarily active in the night, but sometimes they are diurnal, as well. Interestingly, coyotes are mono-oestrus animals. Once they found their partners, the pair bond remains for many years.
Canis lupus familiaris is the scientific name of the domestic dog. Their ancestors were grey wolves and they became domesticated before 15, years. Dogs live all over the world and are not native to any particular country. They vary drastically in weights and sizes according to their breeds. In fact, dogs have the highest diversity in terms of appearance, size, and behaviours than any other domestic animal.
They can be surprisingly small as well as considerably large; a Yorkshire terrier is only 6 centimetres tall and 10 centimetres long with a weight of only grams, while a Great Dane could measure more than one metre in height. English mastiff dog is the heaviest dog in the world with a weight of more than kilograms.
Moreover, the dog breed decides the coat colour, coat thickness, tail appearance, and their temperaments.
