Pig dashes into street for heart attack victim

JoAnn Altsman had a heart attack and collapsed to the ground. Lulu, her daughter's pot-bellied pig, rushed out of the house, lying down in the street to stop traffic. The pig tried relentlessly to get help, returning to the house to check on JoAnn, only to rush back to the street for help. Finally, one person stopped and followed the determined pig back to the house, where they found Altsman in pain on the floor. She was immediately rushed to a hospital.
