He stresses easily and gives up on things if it stresses him too much. He is learning that he can walk away, so seems he does not growl as much. The only consequence of him walking away is no reward till he re-engages. If he comes back to work, then he gets more reward.
Kevin took him to class this last Sunday. And brought back some god stuff.
He did state that when he came back from a walk, Copper found a toy and started to growl, he doid not have the toy in his mouth, so Kevin told him to get it then gave him the release signal and he gave it right up. What a good boy!!!
