My vet told me of a pack hunting his barn dog-Labrador. Five or six of them circling his dog when he started shooting them. When he'd killed a few of them, the rest finally took off.
This is the vet who chastised me for using a 22 to dispatch sick animals around the yard like raccoons and opossums. He was vehement that I should be using centerfire.
His grand-daughter was the Indiana High school marksmanship champion and got a scholarship to a college with a shooting program. Between her shooting skills and his being a veterinarian, I take his word for it, next time, I'll likely use something like a 223 or M1 Carbine to dispatch animals that shouldn't be around during the day or awake in winter.
