My 6mo gsd mix is very strong, and I am not. He’s been really frustrated today and going after my older dog even after I tell him to leave it. Im proud of myself for getting in there and enforcing boundaries when he acts out. I remove him from the situation and tell him to sit. He’s been trying to bite me but he has good bite inhibition so it hasn’t been painful. He had a bath and it’s too cold outside to walk him right now. So he’s frustrated and full of energy. He’s such a good dog though. He knows when enough is enough and he gets lots of treats when he makes good choices. Even when he’s bitey he stops when I tell him no. I love him so much. He’s growing up to be a great dog. A lot of things are happening while he’s young so I can avoid it when he’s 80 pounds
