On this edition of Hero of the Day, Cam Edwards shares a story from West Pike Run Township, Pennsylvania, where a dog's bark alerted a homeowner to an intruder. The homeowner was lying on her couch early on Thanksgiving morning and heard her dog let out an unusual sounding bark. She turned to see a man trying to enter the house and called for her husband, who came downstairs with his gun. The husband fired a warning shot first, and when the intruder didn't flee, shot and killed the intruder. Originally aired 11/29/2011.
