Dog patrol
EIELSON AIR FORCE BASE, Alaska -- Staff Sgt. Robert Houp and Rin Tin, a military working dog, inspect a truck for contraband during training Aug. 18. Military working dogs here provide anti-terrorism and security to the base as well as to deployed locations worldwide. Rin Tin's day usually begins at 4 a.m. with feeding and a seven-point checkup by his handler. Then comes grooming, a rub down, obedience training and a run through the confidence course before beginning the day on patrol. Sergeant Houp and the 7-year-old 98-pound German shepherd are assigned to the 354th Security Forces Squadron. (U.S. Air Force photo by Senior Airman Joshua Strang)
