I've recently got hooked on Ceasar's dog whisperer show and have been trying to rehabilitate my 8 year old dog.  She's improved amazingly on her walks but there is still a lot I need to train her on. Watching what he does dog after dog, makes me want to stop everything a get to work.  I think he's amazing at what he does, and watching the video you are reminded of that over and over again.  The only negative thing I have to say about the disc set is that unlike when the show airs on the national geographic channel, it doesn't give you an update on how the dog is doing after the session.  Otherwise, it's highly recommended!
