An archaeologist at a museum scolds his small, silent dog, Shep, for supposedly removing a bone belonging to a dinosaur skeleton and orders Shep to bring the bone back, but Shep finds that the place where he buried his most recent bone has been dug up and a bulldog is walking away with the bone in his mouth. Shep chases the bulldog with intent of retrieving the bone, and so begins a battle of wits between Shep and the bulldog.
