I tend to think that a CCW is their for an attack that is life threatening and unexpected. If I truely expected to be attacked on a walk I think I would choose not to go on that walk. If I pull a CCW it's because I have no choice and couldn't have anticipated the perp who is attacking me or mine. If I ever do use lethal force I should be prepared to explain in court why I had to use lethal force to defend myself and my family. I just don't think that shooting a dog that is attacking my dog reaches the necessary level for using lethal force. I would much prefer to use pepper spray or a tazer on a nuisance animal. I'm not the authority on this and this is just my opinion, but maybe it helps.
