Those are all good advice and I guess it doesn't do any harm to follow through with it.
But personally I don't agree with all of them. Especially not that all dogs are out to become top dogs. In fact, I think that way of thinking is being put way out of proportion. Dogs are perfectly well aware of us being humans and them being dogs. For example; If a dog looks a human in the eyes, it doesn't naturally mean the same thing as when they stare each other in the eyes.
I also highly doubt that a dog will "sneak" a paw onto their owners foot, to display dominance and then slowly work himself up from that. The whole point of dominance behavior is that it's a game of display and showing off and making sure your point comes across.
