After a series of destructive acts, the Simpsons lose patience with Santa's Little Helper. SLH is sent to Canine College but proves too unruly and stupid to learn anything. Homer and Marge threaten to give the dog away if he doesn't pass his obedience training, so Bart tries to train him, but SLH refuses to lie down or do any of the other tricks he was taught. Somehow, Bart finally gets through and SLH ultimately passes Canine College and stays with the Simpsons.
