Keep doing exactly what you're doing. I did almost the same thing with Chester and it reall paid off. He's much better about letting me have his bone when I think he's had enough than Millie is. She has growled at me on many occasions about taking the bone from her. Chester has a few times, but we just go back to the NILF program and he submits to me. If I hadn't worked with him from puppyhood though, I think I'd be afraid to take anything from him now.

He's such a little challenge.
