Good catch, but read the bullet right after that one. They contradict each other in a sense. It sounds like you can kill it to PREVENT an attack, but if the attack is already in progress, you can't do anything.
I can somewhat see the logic, but if it were me, I'd shoot the damn thing and bury my dog. When DOW showed up, I'd claim it was after my truck. "See? Not a scratch on it."
