Arnold's trainer was Frank Inn, who trained virtually all of the animals seen in the rural television comedies of the time period, including "Petticoat Junction" and "Beverly Hillbillies". Frank said that he had to use delicate psychology to train his pigs. Unlike other animals, he explained, a trainer can never force a pig to do anything or reprimand them, or else they will come to dislike the trainer and will not perform for them or even take food from them. Arnold won three Patsy Awards for Inn during the 1960s.
