When I got a puppy (!!!) it seemed like everyone recommended this book to me. A lot of it is hopefully common sense for most people (of course I want to reward my dog when he does something right, not punish him for doing something wrong), but the descriptions and scenarios Dunbar provides are so so so helpful. This book isn't just about how to teach a dog to "sit" (though that section has a lot of helpful tips), but how to teach dogs the relevance of commands which then motivates them to comply appropriately. The prospect of training my pup not to be a terror (not that he is, I just don't want him to become one...) seems more manageable now. Also, the prose - though sometimes dated - is ridiculously delightful.
