DNA test confirms animal killed in NY was wolf, not coyote

2. There are also crossbreeds

known as coywolves, in parts of the country, mostly north and some of the northeast, and in parts of Canada. And guess how this happens? Lone wolves, such as this one, may mate with a female coyote they come across. They will settle down and raise pups just like any normal family. The resulting offspring are larger than coyotes and have the smarts of both parents. I saw a documentary on this somewhere.
(As an aside, coyotes are pretty promiscuous, and smart too...in addition to eating your small pets, they will mate with larger dogs, given the opportunity.)
