I was wondering of any of you have ever used bear spray as a dog repellent? We live in a very rural area and my wife and I go on walks every couple of days. A couple of days ago we had a pitbull force it's way through a gate and came charging at us across the street. I pulled my S&W .40 and when it got to about 10 feet I fired into the dirt next to it and it stopped, probably from the noise. We slowly backed away and it finally lost interest. My wife said she would have felt really bad if I had shot it. So maybe bear spray would be a better alternative. What do you think?
