There is a story where Abe Lincoln killed a dog with a pitch fork. The owner asked why he didn't use the other end of the pitch fork, Abe replied "because he (the dog) didn't come at me with the other end".
I don't like shooting dogs, but I'll use the fork part (gun) not the handle end (pepper spray) if the dog comes at me with the biting end.
