yeah one of my neighbors lost two sheep to a pack of pit bulls. the sheep were shredded. i didn't even know that domestic dogs would go after livestock like that but our landlord swore it was dogs and not coyotes. and my own dogs killed my first hen and two stray sexlinks that i had rescued when they came into m yard all skinny and pitiful.
My neighbor has a habit of letting his dogs roam free, and although they're generally friendly, now that I have chickens I'm always worried they'll decide they want a fresh chicken dinner. I warned my neighbor that I will shoot to kill any dog that comes near my chickens. That was three months ago and his dogs, amazingly, have not left his property since then. Another neighbor baked me a cake in thanks for FINALLY getting those dogs under control. I guess I wasn't the only one irritated.
