Here is "down". He used to have to follow a treat to the floor from a sit position. Now I only have to lean over a little. With practice, I'll just say it and he'll hit the floor. We use down a lot in public. He has to lie down under tables, chairs, and my desk at work in order to stay out of the way.

This is an excellent "down". He's not laying on his legs ready to jump back up. He's laying over on his side relaxing and has no intention of getting up fast. Perfect!
