Luke the Dog (1913–1926) was an Staffordshire Bull Terrier that performed as a recurring character in American silent comedy shorts between 1914 and 1920. He was also the personal pet of actress Minta Durfee and her husband, the comedian and director Roscoe "Fatty" Arbuckle.

Roscoe Conkling "Fatty" Arbuckle was an American silent film actor, director, and screenwriter. He started at the Selig Polyscope Company and eventually moved to Keystone Studios, where he worked with Mabel Normand and Harold Lloyd as well as with his nephew, Al St. John. He also mentored Charlie Chaplin, Monty Banks and Bob Hope, and brought vaudeville star Buster Keaton into the movie business. Arbuckle was one of the most popular silent stars of the 1910s and one of the highest-paid actors in Hollywood, signing a contract in 1920 with Paramount Pictures for $1,000,000 a year.
