The best dog training book that I found is an e-book. The advantage that it has over a paper book is that it has videos as well - so you can hear and see what you need to say and do, and How to say and do it.
It's by Dove Creswell, and is for puppy and adult dog training. Dove works for movies and commercials, so plenty of credentials.
The lessons I found to be fun, interesting and they make sense.
