Actually, I wasn't quite correct on the breed. Greyhounds are the primary dog for coyote hunting. My Dad used to raise and race greyhounds, and they hate anything that's not human, including each other. Fight at the drop of a hat, which is why they're always muzzled. But they are wonderful with humans. Nothing like being 10 yrs old and having 20 dogs trying to lick you to death. Dad raised a dog in the 40's (He worked for my Uncle's kennel), that became a world champion, is in the hall of fame. That dog would be worth a couple of million today.
