In our private lessons, I try to focus on teaching the human how to communicate with their dog, rather than focusing on teaching the dog how to sit, down or stay. I will definitely teach how to train your dog how to do those things, but training boils down to the owner/dog bond and how they communicate together. If that bond is broken or just not there, the dog will be less likely to want to interact with the owner, than if the bond is strong and fluid.
