I once had a black puerto rican pit with a massive scar down it's face. Sweetest dog I'd ever owned. Re-homed him when I got kids.

Finding a new pitbull attack thread to read through is like pulling your jeans out of the dryer and discovering a ten dollar bill!

sure. Probably overkill though. Dogs, like bears, have many more times the receptors in their nasal cavities that a human has. Makes them much more sensitive to things like pepper spray, iirc. So regular pepper spray should be more than adequate. Cheaper too.

The one advantage to bear spray, and you kind of touched on it, is the fact that the canister is much larger than normal, so if you are attacked by multiple dogs, you have more ammo, as it were.
