Unknown dog comes out of nowhere to help a woman in car wreck

Next time you are in need of help, your guardian angel might just be a stray dog.  “When Shannon Lorio crashed her car on a rural road, a stray dog emerged from the woods and came to her aid. Pulling her out of the car and dragging her over 100 feet back to the street, the dog enabled Shannon to flag down a passing vehicle and save her life.” from the source.
