i am hoping it will reduce his testosterone scent, he has been attacked twice in a couple of months for what I can see no reason. he is not afraid to go up to any dog and is a bit full on if they show signs of submissiveness, but if a dog looks at him with 'that' look or barks/snaps at him he's off like Usain Bolt to hide behind me or the bushes! he's absolutely fine with little dogs his own size but big ones he seems to have to prove himself. he was very roughly rolled and grabbed hold of when he was about 6mths by a boxer, he cried :-( he's now 2yrs.
