That's acool dog, the thing he did at the end reminds me of what my 7 Month Labrador sometimes does when he get's stuck on a tree with the long leash...he then tries to either uproot the tree or get out of the collar and moves in just about the same way as yours did when he was supposed to lie down...
Well, and about the original question: I'm a Dog person, I don't mind cats, but I would never get one. A pet I can't train to do tricks and also to obey commands is no pet in my book...
