Why is my dog bullying puppies?

Some dogs consistently start fights with small puppies to prove they are bigger and stronger, even if they play fine with older dogs. In other cases, a new puppy will persistently chase an adult dog away from its owners until she hides behind the couch. This relentless bullying often becomes so severe that spouses want to get rid of the instigator.
