White Dog is a 1982 American drama horror film directed by Samuel Fuller and written by Fuller and Curtis Hanson, based on Romain Gary's 1970 novel of the same title. Executive Producers were Edgar J. Scherick and Nick Vanoff. The film depicts the struggle of a dog trainer named Keys, who is black, trying to retrain a stray dog found by a young actress, that is a "white dog"—a dog trained to make vicious attacks upon, and to kill, any black person. Fuller uses the film as a platform to deliver a message against racism as it examines the question of whether racism is a treatable problem or an incurable condition.
