It is a sad moment when a young boy discovers he doesn't have enough money to buy the waggely tailed dog he sees in the pet store window. Nothing but that waggely tailed pup will do as a pet for the boy, so he's off to make some money to buy the dog of his dreams! Misadventures follow and by the end of the week the boy has less money than when he started. Thinking he will just say hello to the doggie in the window, the little boy finds the dog is gone. Someone else has bought the dog for a very special son to thank him for all the nice things he has done. Who could that lucky boy be?
