An Excerpt from the LA Times newspaper follows – — Los Angeles Times Aug. 2, 1925 and June 25, 1929
Strongheart, born 1917 in Wroclaw, Poland, died June 24, 1929 in Hollywood, was a veteran canine actor, trained in the kennels of the Berlin police department. He had a gallant record of service in the German Red Cross in World War I.
Strongheart’s first picture, “The Silent Call,” met with sensational success. Among his subsequent starring movies were “Brawn of the North,” “The Love Master,” “White Fang” and “North Star.”
The veteran canine actor, especially beloved of children the world over, was the first animal to obtain stardom on the screen. His sensational success was the signal for a mad rush to Hollywood by the masters of his canine brethren.
The name Strongheart was decided upon by the publicity department of the motion-picture studio where the dog first worked. His original name, Etzel Von Oeringen was too long and complicated.
Strongheart has been so well trained in police methods that he can tear the clothing of a person to shreds, knock him about in a terrifying manner, and (for screen purposes) kill him deader than a door nail without leaving a scratch to tell the story.
