Copper loves to play jokes on my nephew. Nathan doesn't share very good and throws too many temper tantrums when he doesn't get his way. Copper decided to give him obedience lessons!! When Nathan tries to get the ball from Copper, he lets him get just within reach and then runs off with it. The funny thing is he only does it when Nathan has been screaming at him to give him the ball. If Nathan is playing nice, Copper runs, fetches the ball and drops it at his feet. Copper knows that your supposed to be nice and he's just doing his job to promote peace in the house!
