Strongheart was born in Germany and trained to work for the police and the Red Cross during World War One. After the war, the dog's owner could not afford to keep him, so he placed him with a kennel in the United States. Director Lawrence Trimble saw Strongheart and persuaded screenwriter Jane Murfin to purchase him. Trimble trained Strongheart and directed him in four movies. Strongheart got burned by a studio light in 1929 and died from a tumor caused by the burn. Strongheart was one of the first German Shepherd dogs to star in a movie. The Silent Call was Strongheart's first movie.
