I have no intention of "putting up" my dog against a bear.
My point was that if I was attacked by a predatory bear I would have an ally in my dog.
It might save my life.
You don't sound like you have much experience in these matters. If you want to protect yourself from bears, get a gun. A p*ssed-off bear in the wild is no joke. If you care about your dog, you'll keep it away from bears. It might intimidate a cub, but it won't do you any good against an adult.
