Pluto was the real name of the dog who played Charlie in this Dennis the Menace program. He also happened to be the same dog who gained television immortality five years later in 1964 for playing the bloodhound, Blue, in "The Andy Griffith Show" ("Barney's Bloodhound").
Charles Barton, who directed this program, also directed that same year the smash-hit comedy feature for Walt Disney Studios, "The Shaggy Dog," for which he was nominated in 1960 for the Director Guild Award for "Outstanding Directorial Achievement in Motion Pictures."
