I have no children. My dogs are my children, and I'd defend (or avenge) them te same as anyone would his own child. I'd probably end up in jail, but so be it.

I got in the mifddle of two big dogs once, trying to break up a fight. Once the chow had been kicked in the ribs a few times, he broke off the fight and high-tailed it. A dog, no matter how big is no match for a grown man. There are other ways to handle the situation. If attacked, beat the dog with a stick, go find the owner and shoot him, not the dog.
