Teddy the Dog or Keystone Teddy (1910/11 – May 17, 1925) was the most famous animal actor associated with the Mack Sennett studios. The Great Dane was one of only three (with Mabel Normand and Roscoe Arbuckle) of the studio's stars whose name appeared in the title of a film (Teddy at the Throttle). He performed chiefly in Sennett comedies, but he also appeared in dramatic films including Stella Maris (1918), The Strangers' Banquet (1922) and A Boy of Flanders (1924).
