That's true. They will hunt down and stomp coyotes to death. And the unfortunate thing is, you can shoot coyotes all day long and it won't help; they just breed more and faster when you cut their numbers back a little. Getting a couple of llamas is easier, they're on watch all the time when you can't be.
LOL...you must have some pretty wimpy yippee dogs if they can be stomped by a donkey or llama.
