As a long time bull dog owner and hunter of hogs with dogs using some high prey driven bulldogs for catch duty, I realize a dog of mine could go on the attack due to prey drive stimuli etc...
Generally perfect non aggressive angels but not the sort of dog I can run loose like 5 of my indoor outdoor pet dogs.
Even with my indoor/outdoor pet dogs, if they go "broken arrow", if the victim don't take them out, I sure will...
I ain't tolerating it from mine and I sure won't tolerate it from others.
As for CCW, I have never heard that it cannot be deployed against a vicious dog.
