The relationship between human and canine unfashionable deep roots. Converging archaeological and genetic evidence indicate a hour of domestication in the behind time Upper Paleolithic close to the Pleistocene/Holocene boundary, between 17,000 and 14,000 years ago. Fossil bone morphologies and genetic analysis of current and early dog and wolf populations have not yet been able to conclusively determine whether all dogs descend from a Canine Vaccinations single domestication event, or whether dogs were housewifely independently in more than only location. Submissive dogs may have interbred with local populations of luxuriant wolves on considerable occasions (a process celebrated in genetics as introgression).

The skin of domestic dogs tends to be thicker than that of wolves, with some Inuit tribes favouring the erstwhile for use as clothing due to its greater resistance to wear and tear in harsh weather. Unlike wolves, but like coyotes, domestic dogs have sweat glands on their paw pads. The paws of a dog are limited the greatness of those of a wolf, and their tails tend to curl upwards, another trait not found in wolves.
