A 7-year-old Tennessee boy, lost and shivering in the cold, cuddled with his dog to stay warm before rescuers reached them.  Dominic Jeffries was out with his pooch Coco when they became caught in a space between bushes and a wall near their home last week in Cordova, Tenn.  Temperatures dipped below freezing but Dominic held on right with Coco, his family’s black Shih Tzu, officials told ABC News.
