My lovely (un-neutered) Irish setter boy who is 3 and a half has in the last 6 months had 3 incidents of really growling and showing teeth / snapping his jaw at and giving all the signs he’s going to bite in reaction to another intact male showing a non friendly stance, or trying to hump him.
he’s nearly always as good as gold, he’s generally fine with other un-neutered dogs but after the latest incident in the park I’m wondering what else I should do?
would neutering or the injections to lower testosterone help?
