Sully's obedience work today was pretty clean! He heeled up just fine and he tolerated walking with the big dogs with quiet aplomb after his initial cussing. He would get corrected every time he lunged or barked and soon he settled in. I am certain he would be more difficult to calm down if the other dog were reacting to him too but this was a good first day.
Tomorrow we are working on Implied Stay, Come, and Down with his obedience and he is going to get some off-leash socialization time with my dogs to practice being calm around calm dogs. He will only get attention from me when he is acting calm and under control and he won't get any positive feedback for acting anxious, scared, or for cussing (growing under his breath or growling) or lunging at other dogs.
