Synopsis by Hal Erickson
The weekend is approaching, and the Petrie family plan to relax with a trip to the country. All this changes when Rob (Dick Van Dyke) is talked into caring for Larry, the huge, unkempt German Shepherd owned by fellow writer Buddy (Morey Amsterdam). It doesn't take long for Larry to make a total pest of himself, and even little Ritchie (Larry Mathews), who loves dogs, begs Rob to get rid of the mutt. But things take a surprising turn when Buddy comes back to collect his pet.
