Been packing a pistol and bear spray for the idiot neighbors dog. Told him a couple weeks ago I was gonna get him with one or the other. Took the pups for a walk, and he came after us dragging his chain. I laid out a fog of spray, except the can was getting low. (I sprayed a couple other dogs last summer) Yeah, a sorry mist goes out a few feet. Dogs whirling around me. I get a nice 'whiff'. Eyes water, nose runs, face burns. Dog tried it one more time and I gave another squirt and stepped back. He was done, and so was I, LOL.
All that said, I've used bear spray on dogs several times, and ain't really that impressed. I'll use it to maybe prevent having to hose one with a gun, but I will never substitute that stuff against a bear over a firearm.
Forty Fours and Forty Fives rule. Well, and nine, nines for the dogs. Blading.
