It is very difficult to find good information regarding this breed, especially in book format. This book is great! If you are considering sharing your life with a German Pinscher (GP,) I highly recommend reading this book first, in addition to talking to as many owners and breeders as possible. GP's are a big challenge and are not the dog for everyone, but for the right "parents" they can be pure joy! For the current parents of a GP, the book offers additional training information and insight to the GP mind. I truely enjoy this book and refer back to it often. I highly recommend it.
