Here's something that happened to me today that I would like to get feedback on... I live in Polk County and was walking my dog this morning, on a leash, when a pitbull that was loose began approaching us down the street. My wife retreated with our dog but the pitbull continued toward us, increasing his pace. I was carrying my gun and was ready to use it when the pitbull would reach a closer range and if he did not stop. When he was about 25 feet from us, his owner arrived in a pickup and was able to get him before he got to us. Question: Would it have been reasonable and legal (as I believe it would have been) to have shot at the dog when he was at a closer distance (remember, he was charging at us)? We were retreating and the dog was increasing his pace. My wife and I both felt an increasing and imminent danger to ourselves and our dog. Any feedback that we can get on this would be greatly appreciated!
