Anthony, I do a little of what everyone is suggesting with my crack puppy. I did start with what Michelle has suggested in a controlled environment, because he is so difficult to keep focused.
What really polished it up was even after he fronts and I reward, I'll back a step and repeat again. I do it a couple of times. That way he waits at the sit (in front of me) for additional instructions from me and stays focused. Sometimes I'll throw in a single reward then we'll run off to play. But I don't ever reward and end it there. I will when he matures, but right now my game is to keep him focused on me.
