I was so glad to find a copy of this book. I have a friend that has a pup and I highly recommend this book in order to train his dog. I have used it on two of my own and they were both great dogs and very easy to train with the instructions in the book. I had loaned my copy out to someone years ago and never got it back. I bought a copy for myself and another for my friend with the new pup. Absolutely the best book I have ever seen with great results.
