As is 'people spray'. I carry a tiny pepper sprayer 24/7 as a staple, just like my dinky pocket knife. You can hose down several people and walk away, no consequences, unlike shooting somebody. Yeah, it's close quarters, but most people attacks are.

I've hiked Alaska and Canada. Bears weren't ever a problem (saw plenty!) but one of the party always carried a rifle or shotgun with slugs/00. A slung Remington 870LW 20ga. is lighter than many big hand guns and doubles as a club or tarp pole. In the park I care for, dogs are the main issue and I carry a 9mm just like the cops/animal guys do. Spray don't work well on dogs. I have been attacked, twice...blindsided both times. Fended of a pit bull with trekking poles, and the rottweiler with pruning loppers.

Here in Texas, Mexican Black bears are so shy, you are lucky to see one. Mountain lions are here too....I don't bother arming myself for either lions or our bears. I'd rather take their picture.
