My cousin had neighbors rotty kill 15 laying hens. The dog was stupid enough to hang around and bury them. He was still on his place when he got home he shot the dog on site. The owner was pissed off that he had shot his dog, but shut his whinny ass up when he was told had to pay $5.00 a bird.
Shoot the damn dog and bill the owner.
