Pixi, Pea Wea, Lulu and Snorkie may have been pigs, but their owners still were hoping they could acquire some good manners. So these porkers, of the Vietnamese potbellied variety, were enrolled in Karyn Garvin's eight-week-long pig-obedience class, held at Reid Park's Handi-Dog Pavilion. The students were taught how to heel, sit, wait and come, just like their canine counterparts. They even had to sit still for one minute, as well as lie down and stay down for 30 seconds. While attending class on April 12, 1992, Snorkie, in the foreground, received a treat for obeying a command while the rest of the class lined up. Snorkie placed second in the graduating class.
