Great book, good examples and do it yourself section at the end. However, frequent mentions of her company sounded a bit like a paid advertisement, and gave me an uneasy feeling. I watched the videos on the website linked from the book, and found them less impressive than the stories told about them. E.g. The blue bowl "sit" cue didn't work that well, and was done very sloppily. The theory behind clicker training is absolutely fantastic though, and there is a lot one can learn from this book. Personally, I liked the "Don't shoot the dog" better.
