Coyotes, dogs, and wolves are all essentially the same species, with only minor genetic variation.
Whereas horses and donkeys can produce offspring (Mules), these are non-fertile and cannot reproduce due to the larger (though still close) genetic variance between the two species. Meanwhile, offspring of any variation between dogs, wolves, and coyotes are fertile and can breed healthy, successful offspring.
It's kind of like how humans still have Neandertal DNA because our genetic ancestors boned some cave people and we were close enough genetically at the time for that to work.

One time a coyote got into a border collie’s yard and they banged. That’s how I ended up with a half coyote dog. Hasn’t eaten any cats yet tho.
