Duke learns how to shake

I met Duke Friday afternoon. He is a loner type dog and I wanted to try to draw him out of his shell. After asking him to wait and not lunge at an open door and having him comply I realized this is a very smart dog. On my first visit Saturday I began working with him to teach him how to shake. Here he is one day later on Sunday afternoon shaking with convidence and enjoyment. Duke is a great dog to pet sit for.
