OP - all suggestions above are really great. I can say that I followed Jane's (onyx'girl) advice to build ball drive for my pup and it worked like a charm. Having a ball on a rope helped me make the ball more interesting for my pup. Even if I was just dragging it around by the rope. He'll now fetch and retrieve till my arm falls off.
It was important to remember to stop the game BEFORE the pup tires of it. As soon as you see the enthusiasm start to drain, finish the game.
