Lulu, the potbellied pig who saved her human's life.

When Jo Ann Altsman suffered a heart attack while vacationing in the Pennsylvania woods, Lulu, her housebroken potbellied pig sprung into action. After crying for a minute,Lulu, broke through the gate of the mobile home they were in and ran toward the street. When a car would approach, the pig would walk into the road and lie down. 
Each time the car didn't stop, the pig ran back inside to check Jo Ann and then back to the road. A motorcyclist stopped and followed the pig to Jo Ann, where he used his phone and he called the 911.

What a brave piggie!!
