PETERSON AIR FORCE BASE, Colo. — Gina was a playful 2-year-old German shepherd when she went to Iraq as a highly trained bomb-sniffing dog with the military, conducting door-to-door searches and witnessing all sorts of noisy explosions.
She returned home to Colorado cowering and fearful. When her handlers tried to take her into a building, she would stiffen her legs and resist. Once inside, she would tuck her tail beneath her body and slink along the floor. She would hide under furniture or in a corner to avoid people.
A military veterinarian diagnosed with her post-traumatic stress disorder — a condition that some experts say can afflict dogs just like it does humans.
