I have read both of Cesar's books and have really learned a lot from them. His techniques have impacted my dog's life. His 1st was a lesson in dog behavior and how to deal with their issues that usually lead to bad behavior. This new book helps both the dog and the human by establishing how to be the leader in your dog's life. He gives many examples of how to be a calm assertive leader as well as why this state of mind is so important. I REALLY recommend this book and the book "Understanding: Train of Thought" to all.
