Payton Is making progress. He is learning to be responsible for following his owners instruction as to not become overstimulated which was the reason for his biting history. Payton is a smart but somewhat willful dog. At one point during his training he threatened to bite me rather than lie down when commanded to do so. I was glad this happened because for the first time in his life he was held accountable at the optimal moment of error, and had to go right back to work anyway. It was finally communicated to him that aggressive behavior wasn't productive and he was still going to have to follow through. Payton is wonderful with the children in the household I believe that his breed has a very high level of work drive . Before he started training I think he believed that being protective was his job. I give his owners a lot of credit for working so hard with him. Many people would have just chosen to give up on him. Their dedication and training with him are really paying off and Payton is now responding really well to direction.
