Brady is doing this too. For example, when we put his breakfast or supper down, we always have him do a couple of things first before we release him to eat. Lately I put his bowl down and he goes into this act of doing 4-5 different obedience things before I've even said anything...sit, down, shake, circle, spin...all on his own, then his sits and looks up at me with those sweet eyes as if to say "well, see what I did? I'm a good dog right?" It's really a riot and I love that he offers me these behaviors, but what I usually do is, after he is done with his "performance," I then ask him to do a couple of different things like high five and back up, and also re-do a couple of the things he first did like sit or circle but tell him to wait after each one so he understands he's to do them on my cue.
