The most common and popular book that you will find is by Wolters called "Gun Dog". Although Wolters book is the old stand by,I wouldnot read it in a literal sense. His book is based on what a dog should be able to do by a certain point in a dogs life. I've seen first hand several people who have been overly hard on their dogs because the dog couldn't do what Wolters said it shouldbe doing at acertain age. Each dog is different and so is it's development. Be patient! Some dogs mature faster than others, even within the same breed. Be patient with your dog for at a minimum the first year before you raise your expectations to the level of "a finished gun dog".

Here is a really good book that I read that also helped me with my dog for it's first year.

"How to Help Gun Dogs Train Themselves" by Joan Bailey

If I could make a recommendation, tryTheRick Smith method for your dog. It incorporates a soft hand for training in a logical and easy to follow process. I utilize it to train my dog. Rick's methods build off of his dads (Delmar) and he offers seminars all over the country to help you in better understanding his approach. Delmar Smith has a book that can be found at Barnes and Noble. Rick is in the process of writing one now and it should be out within the next year. Here is a link to his website for information on Ricks videos/DVD's and seminar schedule.
