The Case of the Howling Dog is a 1934 American mystery film directed by Alan Crosland, based on the 1934 novel of the same name by Erle Stanley Gardner. It is first in a series of six Perry Mason films Warner Bros. made between the years 1934 and 1937.

The film stars Warren William and Mary Astor. William would star as Mason in the first four films: after The Case of the Howling Dog there were: The Case of the Curious Bride (1935), The Case of the Lucky Legs (1935), and The Case of the Velvet Claws (1936). Ricardo Cortez took over the role of Perry Mason in the fifth film, The Case of the Black Cat (1936), then Donald Woods became Mason in the sixth, The Case of the Stuttering Bishop (1937). Each film in the series would feature a different actress portraying Della Street except for Claire Dodd, who played her twice; in this movie Street is portrayed by Helen Trenholme. The characters were revived in the popular CBS television series Perry Mason which starred Raymond Burr as Perry Mason.
