Juan Heriberto Trevino, 14, was attending a summer camp in Mexico's Sierra Madre Oriental mountain range this week when he became separated from his group.
After wandering off in search of firewood, Trevino slipped and fell down a ravine. Though injured and disoriented, he soon realized he was not alone.
Max, whom Trevino met only a short time earlier at camp, had been accompanying the boy on his ill-fated trek. When he fell, the loyal Labrador retriever followed him down.
