You'd be surprised what "reinforces" a dog's behavior - sometimes it's what you do without realizing it (sucking in your breathe or being tense) - not what you say - that makes a difference. I've been around dogs all my life and had to change some of things I did because I learned I was adding to a certain problem without meaning to... I really like this book because it focuses on reward for good behavior - not punishing the dog just for being a dog.
