13 Month Old GSD Misbehaving
My 13 month gsd, Ari, is constantly getting into trouble. His favorite things to do are to get in the trash can and to pull/eat stuff off the refrigerator. He knows he is not supposed to do that, as I reprimand him when he does, and he will try to run away from me if he has something in his mouth. I'm not sure what I should do to discipline him, or to get his behavior to stop. The other issue is that he does not behave this way at all if my boyfriend is around. He is the perfect dog then, it is only when it is just me around. I know he sees my BF as the "alpha" and me as his pack mate. When I catch him doing things he isn't supposed to be doing I make sure to use a stern voice and say "no". Beyond that, I'm not sure what to do. We have always tried to use positive reinforcement when we train him, so I'm not sure how to handle this kind of behavior.
