Snoopy is becoming a real problem. He is getting on everyone's nerves and won't listen to Charlie's commands. Now it's time for obedience school. Chuck sends Snoopy to live with Peppermint Patty, and she teaches him one big lesson in manners and self control. Unfortunately, as soon as he runs away from the torture he is dealing with at Patty's, he goes back to his old ways which, in the end, everyone missed while he was gone.
