My ex inlaws had a dog that was an inherited dog (a long time ranch worker) He was 1/2 shepard 1/2 coyote.... meaner then hell. but I can tell you that he could intimidate ANY full breed.
no and dogs rarely breed with coyotes (sometimes with wolves in captivity, very rarely wolves in the wild or dingoes). they have to at least be the same genus to breed so dogs don't breed with hyenas, foxes, etc..etc..
possible foxes too.
lottie yes the can their are several of them out there, they also breed zebras and donkeys
tigers and lions to make tigons and ligers
