A coydog is a canid hybrid resulting from a mating between a coyote and a dog. The term is sometimes mistakenly used for coywolves, which are common in northeast North America, whereas true coydogs are only occasionally found in the wild. This is due to the mating cycles of dogs and coyotes not coinciding, and coyotes are usually antagonistic towards dogs, with even captive specimens having shown reluctance to mate with them.
