Robert Houp and his dog Rin Tin inspect a truck for contraband during routine training at Eielson Air Force Base, Alaska, on Aug. 18, 2004. Rin Tin is a 7-year-old, 98-pound German Shepard. Rin Tin's day begins at 4 a.m. with feeding, followed by a 7-point check-up by Houp, grooming, a rub down, obedience training and a run through the confidence course before beginning the day on patrol. At the end of the day, he goes through a de-stress period with Houp by playing with his toys and playing in the grass.
