Apparently you're not familiar with the Dog Whisperer. Yes, there is a pecking order, dogs are pack animals, and there is a pack leader or alpha dog, he is usually your first dog. Cesar Milan recommends that the dog owner become the true leader of the pack in order to eliminate fighting and aggression. There are many methods to do this, but mostly its calm, assertive, not aggressive, by the way, behavior. No screaming, shouting, or hitting allowed. Dogs show respect to the pack leader, and feel safer when there is an established pack leader.
