After years of on-the-job clashes with cranky canines, mail carrier Wilson Daniels (MacMurray) sees man's best friend as his worst enemy. This makes for one hairy situation when a magical ring accidentally transforms his teenage son Wilby (Kirk) into a lumbering sheepdog! Can Wilby break the spell and foil a team of international spies, or will both he and his dad wind up in the doghouse? Packed with sidesplitting antics, slapstick chases, and hilarious sight gags, this madcap adventure will tickle the funny bone of every two- (and four-) footed member of your family!
