However, Trigger appeared in many other Roy Rogers films, including:
* "The Cowboy and the Indians" (1949)
* "The Golden Stallion" (1949)
* "The Black Castle" (1952)
* "The Law and the Lady" (1953)
* "The Last Outpost" (1951)
* "The Yellow Tomahawk" (1954)
And many, many more!
Do you have a specific movie in mind? Perhaps you can tell me more about it, and I can help you narrow it down.
