I can just see myself dodging traffic while dodging and kicking a pit bull. No thanks. I think I'll stick to chemical warfare.
PS. Good luck with a "kick" to the head. I have a friend who is a cop. He said it took three bullets to the head of a pit bull to put him down.
I'd wager he missed and hit neck/jaw/body the first two times. Bullet + brain = dead. A single bullet would kill a grizzly if you could penetrate his skull.
