I highly doubt that Victoria Stillwell said anything about "dominance" Leadership yes, not dominance.
I record them on my DVR so I'll have to watch that one. Usually her solutions are drastic and temporary, until the dog learns what is expected of it. Typically she is dealing with dogs who have been allowed to run the show and need to learn otherwise. We learned something similar in training classes called NILIF - Nothing in Life is Free AKA No Free Lunch. In other words, you ask the dog to sit, come, down before you pet him, feed him, go for a walk, etc. You ignore bad behavior (like barking for attention) and reward them for good behavior (responding once they are quiet). Eventually the dog learns the house rules and the routine and you can lighten up. Loki knows he sits while he gets his leash on and off, so we no longer have to do NILIF for that (no sit=no walk) because he just DOES what he is supposed to do or what I ask him to do.
Anyway, I like that show.
ETA: Walking in front of your dog doesn't show the dog anything, except that you are weird. Dogs can respect us as leaders and walk in front of us. That sounds like it came from Cesar...
