Snoopy's persistent mischief is angering the other kids in the neighborhood, and they all demand that Charlie Brown do something about it because "He's your dog, Charlie Brown!"
In a letter to the Daisy Hill Puppy Farm, Charlie Brown writes that he is going to send Snoopy back for a refresher course in obedience. Snoopy loathes the idea, but Charlie Brown tells him it is for his own good. As it is a two-day trip, Charlie Brown calls Peppermint Patty and asks to let Snoopy stay there for one night en route; Peppermint Patty agrees, but a scheming Snoopy decides to stay on and has her waiting on him hand and foot, which confuses her.
