It sounds similar to alpha rolling.. which can be really dangerous. When we adopted Kaedyn, he would try to bite if I towered over him (my mistake). I didn't dare try to make him to submit because I know there would have been blood if I had tried.

I teach all my clients how to become alpha through NILIF. NILIF just seems like a smarter way to go because alpha rolling or doing the dominance down is really just forcing the dog to submit. He hasn't gained any respect for you as a leader. NILIF though shows the dog that you are the source of everything good and does eventually gain his respect.
