Dog Health Questions: Dog training specifically for retrievers?

I have a one year old black lab that I am training to be my hunting partner. We are working the basic commands right now, but I have noticed that when I throw his ball he will chase it but not retrieve it. I haven't come across a lab yet that will not retrieve. How can I correct this behavior to train my pup to be an outstanding gun dog?
