This may be one of the most amazing acts of canine heroism we’ve ever heard.

Three-year-old Victoria thought her dog, Blue, ran away, and she somehow got out of her Arizona house to go look for the dog. For fifteen hours, rescuers scoured the area looking for Victoria. They finally found her lying in a dry creek bed, and right next to her was Blue, keeping her safe.

Blue and Victoria had been together ever since she was born, and the two share a special bond. Rescuers say she was a very protective for Victoria at first, and wouldn’t let anyone get near her. They believe the Queensland Heeler stayed with Victoria all night, keeping her warm and alert through the frigid February evening.
