Beau has started chasing behind me and nipping at my legs and ankles. I give a firm "NO! But so far that hasn't stopped it. He was biting my hands real hard but I have just about broke him of that. I let him mouth on me for a little bit and he is satisfied. He also loves to bite at my hair. My hubby says to tap him on the nose when I say no, but I don't believe in negative reinforcement. What do you all suggest? Is hubby right? HELLLLLLLLLLPPPPP!
