Pit Bull came charging from nowhere, didn't know whether it was coming after me and my kid or my dog. I picked my kid up in the air and it attacked my dog. Within 10 seconds the owner ran up and was able to get his dog off mine. I decided right then and there to get my CPL. Not for fear of my own life, but rather to be sure I can instantly end any immediate threat to my kids life. What if my dog wasn't there and it grabbed my kid before I could? Empty handed could I disable the dog before it disabled my kid? I dont have to wonder anymore.
