My neighbor has a very territorial dog. The dog does not care if you are on your own property or walking alongside the road. When he notices you, he will run towards you barking and then when he is close enough, he will snarl, bare his teeth, and growl and then stop right when he is close to you. He has gotten so many complaints from my fellow neighbors about his behavior. He won’t bite you but I am scared that he may one day. Would it be safe for me to use a correction spray to possible deter him and confuse him once he starts charging? Is there any way to show him that I mean no harm? I don’t want to hurt him but he frightens me. Any help is appreciated!
