Dog Protects Missing 3-Year-Old Boy

A dog in North Dakota is being hailed as a hero for sticking with a 3-year-old boy when he wandered off on his family's 10-acre farm. The boy, Carson Urness, and his dog disappeared at around 7:30 p.m. Monday after his mom let him out to play.
Not long after, Courtney Urness realized Carson and Cooper were missing. When she and her husband couldn't find Carson in a frantic search, they called authorities for help. They quickly started an aerial and ground search with the help of 200 neighbors.
At around 2:30 a.m., the temperature had dropped to 40 degrees and organizers were about to call the search off for the night when a four-wheeler doing one last sweep of the farm saw Cooper stick his head out of the tall grass in the middle of a field about a mile from the house. They found the dog laying on the boy. "[Carson] said, 'Mom, I was really scared but Cooper laid on me, he kept me warm,'" said Courtney
Urness. Cooper might have been returning a favor for the Urness family. They rescued him when they found him as a puppy wandering by the side of the road three years ago. - Watch it at ABC News
