Inseparable pair
Christopher Carswell and his service dog, Bronx, maneuver through a canine obstacle course at Moody Air Force Base, Ga., July 10, 2012. Christopher, an epilepsy patient, has been paired with Bronx since 2010. Bronx helps Christopher with his mobility and has even detected some of his seizures, allowing him to receive medical attention quickly. (U.S. Air Force photo by Staff Sgt. Jamal D. Sutter/Released)
