 According to the American Humane Association, the scene involving  the shooting of General Arroyos horse had no humane representative  present but the AHA spoke with Gregory Peck (qv), who was present  during the entire filming of the scene. Peck described in great  detail how the shocking effect was achieved, and assured the AHA  that the horse, Twister, was not harmed. The AHA went to the  California ranch where Twister is kept so that we could observe him  recreate his specialty fall. Twister performed beautifully and is in  excellent condition.
