What are some of the things your man/owner/master done to train you mentally and physically that has had a great impact? For me, my owner does this thing he calls "cock heeling". He gives me the command to "cock heel" and that basically means my mouth and face must never be less than 6 inches from his crotch if he's moving, or pressed to his crotch if he's not. He could be sitting standing laying down, brushing his teeth, drinking beer, driving his car, anything... I must be right there, ready. What's been effective for you? Please share.
