Read this article that I found about a very brave dog.
Lost Boy is Kept Alive by His Friend’s Dog
Steven and Ethan, ages 9 and 8, were friends out on an adventure with Steven’s dog, Elmo, a 4-year-old Labrador/Collie mix. But their fun outing turned into a nightmare when they found themselves trapped in a swamp. Lost and frightened, Ethan became entangled in brush and mud. A terrified Steven ventured off in search of help. Eventually emerging from the woods, wet up to his shoulders and shivering from the cold, Steven made his way home. Elmo, possibly sensing that Ethan was in worse danger, remained in the woods with him rather than follow his owner home. Elmo remained by Ethan's side providing warmth and comfort, which would save the young boy's life. Local police and their canine unit, a helicopter, fire team and community volunteers all started a search for Ethan. With no sign of him as night fell, the search and rescue team contemplated suspending rescue efforts. In a final attempt before darkness set in, a firefighter saw a pair of eyes in the light. A shivering Elmo and a nearly unconscious Ethan were discovered. Suffering from hypothermia, paramedics rushed Ethan to the hospital for treatment. Throughout the ordeal, Elmo refused to leave Ethan's side, led him away from danger and kept him warm and awake. The police believed that Ethan's survival was a direct result of Elmo's heroic actions.
Wow! What a hero!
