Jerry removes a tack from Spike’s paw. In gratitude, Spike gives Jerry a bell to ring when he’s in trouble. Soon, Tom is acting as Jerry’s servant.

Soon, Tom is taunting Spike (much like Foghorn Leghorn taunts the barnyard dog) and harassing Jerry, who becomes his servant until the leash law is repealed.
