Guess i'm not the only Dog Dad here. Ironically, I mastered the timeout method with my dog. When my lab does something wrong, I tell her "corner" and she goes lie in the corner and looks sad. It took me a long time to teach her this, but it's funny as hell.
Coach Tuesday, try this link below. There are some very knowledgable people there. I've learned alot about dogs, especially labs from this particular message board.
