A pups seem to have A.D.D. really bad. Do you keep your pup on some sort of lead or check cord whenever he is out? Everytime I had my dog out, i kept him on a really short lead. That way he gets the feeling of dragging it around. Don't leave him unattended with it on though. After a while he will not even notice it between you to when throwing bumpers, and will focus more at the task at hand.
