He's Your Dog, Charlie Brown (1968)

When the gang has lost their patience with Snoopy's pranks, they pressure Charlie Brown to act. He decides to send Snoopy back to his puppy farm for obedience training, but Snoopy is less than enthusiastic. He retaliates by going only as far as Peppermint Patty's place who agrees to let him stay for the night. He overstays his welcome as a freeloader which forces Charlie Brown to drag him back home with a firm hand and lease. Snoopy responds by running away for real back to Peppermint Patty's, but he learns that his return visit will be far less pleasant this time... —Kenneth Chisholm
