Pinkerton is teething and nothing made of wood or bone is safe! So his young owner doesn't dare leave him home alone when she goes on a school trip to the dinosaur museum. Her class is wearing dinosaur costumes for the occasion, so she disguises Pinkerton as a stegosaurus. But will Pinkerton be able to resist trying out his puppy teeth on a mouthwatering diplodocus skeleton?
