A touching. heart-warming account of a man and his beloved, heroic Labrador dog. But Echo is something special. With the dedication and persistence of his handler, he is trained to be part of a search and rescue team called upon to travel to disaster areas around the globe to assist in locating survivors trapped among piles of rubble. The bravery of Echo and his handler is recalled in vivid detail as they cope to deal with tragedy and heartbreak in their own ways. Sometimes it can be hard facing up to the challenges and they come perilously close to death but their determination is there for all to see. Years later, Echo is rewarded for his sterling work with the Pride of Britain award, one of such accolades he receives.
