I didn't find this book much use at all, more useful info freely available on google. It doesnt clearly explain the sequence nor importance of timing of rewards.
I did like that it stressed that the idea of dogs wanting to be dominant is incorrect, and i cheered about its more kind approach to dogs. A little like childrearing-kindness and reflection goes much further than hard and punitive measures and is a lot nicer for everyone. I think that point was highlight of the book.
