A mixed Labrador retriever is being credited with saving a 22-month-old who was lost overnight. Tyler Jacobson's mother says he disappeared from their South Carolina home after he left the room she was in to get juice. Temperatures were in the 40s as police searched for the boy, who was only wearing a t-shirt and a diaper. The next morning they heard Tyler crying in a neighbor's yard. The family dog had huddled by him and kept him warm all night.
