This is where I disagree on the debate because I do not believe in the premise.
I have dogs for companionship, and they are little noise makers. But I would never send them out to face the enemy looking for me.
Simply, if the felon is motivated to hurt me, he'll kill the dog. And if that felon is so big, strong and bulletproof, then neither I nor the dogs should be facing him.
In my neck of the woods a lot of pimps and bangers have attack dogs, and I'll bet the reason is much the same in your area. The owner doesn't have the stones to fight his own battles. I won't risk the dog.
