The dogs should be shot and the neighbor held legally responsible for not controlling them. If you can't keep your animals from harming others and what belongs to them, you deserve a stiff fine at least along with hefty restitution to the owner of the dog that was killed. If an animal of any kind is on our place harming my livestock or pets, I will deal with it appropriately (for us the problem is almost always wild animals, but we have the occasional pack of feral dogs to deal with). Too bad the owner of the Jack Russell wasn't there to be able to shoot the pit bulls.
