There were some helpful tidbits of information in here. However, the first half of the book was about choosing a puppy that's already predisposed to be calm and good-natured. For those of us who didn't get to (or want to) choose, like those that got a rescue puppy or didn't get to visit the litter in person, this is not applicable. Cesar raised the perfect dogs because he'd chosen the most perfect dogs he could find. It'd be nice to see some tips on how to raise *any* dog to be perfect. Perhaps he could have included a rescue dog as part of his pack to show readers what sorts of things he did to help the dog.
