LOL, jumping in late on a thread like this is usually a good way to get your head bitten off, but, here goes, from a biology major. Dogs and wolves and coyotes are, biologically, the same species. They can, and do, interbreed. From a population standpoint, wolves and coyotes are breeds of dogs. From an evolutionary point of view, dogs are a breed of wolves. Ranchers hate coyotes because they maim and kill stock, and on one notable occasion that I winessed, a litter of puppies and their mother. I shall take no position further than that.
