Our puppy has been beaten up twice by older dogs (once there were no physical wounds but the second time he was nipped on the mouth/tongue and bled), and now he’s very skittish around other dogs. We just brought him around another very calm, very well trained GSD and while their interaction was overall manageable, our puppy was not just barking out of excitement and puppy energy, but showing his teeth. Would it be best to keep bringing him around other dogs we KNOW are friendly and rewarding him when he’s being calm? Or are there other ways you would recommend to handle this behavior?
