I agree with the other responder that the book "Water Dog" is an excellent book on the training of a waterfowl retriever. This book is widely looked upon as the "bible" for water retrieving dogs. I have a friend who used this book solely as the basis for the training of his choc. lab and he had excellent results. I have a 3 month old choc. lab pup and I am using this book as the basis for his training.
