A few weeks ago I had a medium sized dog start to chase me, he was gaining on me fast and was worried he would get to the front tire,so I clipped out,took aim,and gave him a shove to the front quarter to knock him off-stride. It worked, and he stopped chasing. Now don't get me wrong, I would never try to to hurt a dog; my black lab is sitting next to me as I'm typing this. It might have been a little more difficult if it was a Pitt Bull trying to take a bite out of my leg. Just wondering what other's experiences were.
