When a rogue sheep dog went after a deer and then my guinea fowl, the game warden told me if it shows up again, shoot it. This is a sheep and cattle area. Rogue dogs are not tolerated. And deer hunting is a high value business, so attacking deer is not okay either. Really depends on the region.
A game warden told me the same thing. If my flock is being attacked I have the right to shoot the attacker.
