The Fonz decides that it's time to get himself a pet and to that end, comes home with a sweet little scruffy dog named "Spunky". Fonz very quickly becomes highly attached to the dog and they clearly form bond.
Unfortunately for Fonzie, he doesn't have his dog for all that long because Ralph and Potsie are silly enough to leave the gate opened and the dog escapes. (Are we actually surprised that this pair left the gate opened?) When Fonz hears that his dog is gone, the boys, eager to save their skins from Fonzie's wrath, tell him that somebody stole the dog which is most unfortunate for the young boy who finds her as Fonz believes him to be the thief.
Not much fun here. Watch something else.
