All dogs bark, that’s what they do. Right now I have 5 and they spend most of their time inside. I have 2 little ones (less than 10 pounds) so when the dogs go out one of us goes out too, we have hawks. If they bark longer than a few minutes we bring them in. If your dog is outside all the time, please bring him in, but if he occasionally barks I doubt anyone can do anything, all dogs bark. As far as cameras pointing at your house, that’s creepy. Maybe you can contact someone in your city to see if that is legal, it might be an invasion of privacy. Good luck!
