Cesar is truly a genuis of what he does.  He has the ability to get the most misbehaved dogs and rehab them to get them back to being great companions.  The only problem with the series that I have is the story is almost always the same.  Aggressive dog, Ceasar comes and teaches the owners to be better pack leaders, thus dog becomes less aggressive.  I would love to see more episodes focused on other problems besides aggressive dogs.
