Wait!

Flash already knows what Wait means. However, we neglected to teach him to Wait at the door until we go in or out. This is all our fault. But it's a problem because he rushes by before we can go out...or in.

Anyway, I've started to make him Sit and Wait until I release him to go out the door. He doesn't like it and pretends he's forgotten how to Sit. I wait until he remembers, then tell him to Wait until I go out the door. Then I tell him it's ok to go out. He does it, but I don't think it's set in his behavior yet. This will take a lot of work and consistency.
