Tennessee resident Rebecca Northern was rescued from near-death last month by a tiny pup named Selena. The Jack Russell terrier was able to pull Northern to safety after she dove into the shallow end of her parents' pool. The impact was so intense that Northern broke her neck.
The dog was a gift given to Rebecca a few years ago after she survived a diabetic coma. She says she wouldn't trade her for anything in the world.
