Teddy (dog)
Teddy the Great Dane or Keystone Teddy was one of the first canine "actors" in American film history. The great dane performed chiefly in Mack Sennett's "Keystone" comedies and behaved on set, according to film crews and fellow cast members, as professionally as any human actor. Teddy is credited with appearing in at least 60 films, nearly all shorts, between 1915 and 1924.
