A coydog is a canid hybrid resulting from a mating between a male coyote and a female dog. Hybrids of both sexes are fertile and can be successfully bred through four generations. Similarly, a dogote is a hybrid with a dog father and a coyote mother. Such matings occurred long before the European colonization of the Americas, as melanistic coyotes have been shown to have inherited their black pelts from dogs likely brought to North America through the Bering Land Bridge 12,000 to 14,000 years ago by the ancestors of the indigenous peoples of the Americas.
