What about using a favorite toy? It's a bit easier to do with some commands then others, but with Betty, we get her to sit for her toy, then throw it for her after she does it correctly, same with leave it, paw, etc.

These are all great suggestions--we use a clicker, but only with treats--I have great ideas from this--thank you all. I am beginning to see hope again.
