A Dog's Life was Charlie Chaplin's initial release for First National Studios, and also his first three-reeler. Chaplin plays a tramp (duh!), who shambles around the cold, cruel world with his dog Scraps. Unable to land a job, Charlie and Scraps cadge a meal from lunchwagon proprietor Syd Chaplin (Charlie's brother). Things take a turn for the better when Charlie befriends down-and-out singer Edna Purviance. After routing a gang of crooks, Charlie and Edna head down the road "Where Dreams Come True" for a deliberately improbable happy ending. Together with
Shoulder Arms and
The Idle Class, A Dog's Life is one of the best examples of Chaplin's wildly uneven First National output. ~ Hal Erickson, All Movie Guide
