Reply #3: The fact that they're pit bulls is irrelevant to the story

[LostinVA]

A few weeks ago, we took our dog to his Saturday herding class, and there was a almost completely devoured sheep carcass in the field. The trainer explained that it was from a pack of coyotes, because the whole thing was consumed. He said a few months ago, a couple pet dogs got into his herd and killed/maimed over 40 head of sheep. A coyote will kill for food, but pet dogs kill for fun. They weren't pit bulls or anything. Any dog is dangerous around livestock, and it's highly irresponsible to let a dog run loose.

Farmers and ranchers don't even leave their stock dogs unattended for long with livestock, because they get "ideas" in their heads.
