The senior wolf does not send the junior wolf three hundred yards away to bring him a dead duck. If the junior wolf finds a dead duck three hundred yards away from the senior wolf, he eats the fucking duck.
Assuming performing the actions typically prescribed in dominance theory (always eat before your dog, always pass through a doorway before your dog, always be situated higher than your dog) will cause your dog to respect you as the natural leader of the pack, it is completely irrelevant to dog training. The point of training dogs is to get them to do distinctly unnatural things. Wolves do not march in formation.
