Shooting an animal that is actively attacking your livestock is legal in my state and many others. Check with your animal control.
I've been in this situation and simply told the owner the facts. Your animal is coming onto my property and harassing, attacking and killing my livestock. If it happens again I'll stop by to ask you to remove your dog's carcass from my property. Simple, straightforward and effective.
First time is an accident, dogs break chains and the owner needs to be aware what occured. Second time is the above statement of fact of what will happen in the future. I've never had a third occurrence.
