What was the name of seabiscuit horse companion?

Seabiscuit's most famous companion was a red-and-white Appaloosa mare named *Trigger*. Trigger was owned by the same man who owned Seabiscuit, Charles S. Howard, and was often seen alongside Seabiscuit at the racetrack.

Trigger wasn't just a companion; she served as a sort of "calming influence" on Seabiscuit, who was known for being a hot-tempered horse. They were often seen grazing together in the paddock, and Trigger's gentle presence was believed to help keep Seabiscuit relaxed and focused.

While Trigger wasn't a racing horse herself, she was a constant presence in Seabiscuit's life and played a significant role in his success.
