Karo, a 4-year-old German Shepherd military working dog, bites his toy, which is being held by U.S. Navy Petty Officer 2nd Class George Simoni, Camp Lemonnier master-at-arms and military working dog handler, after successfully finding contraband during a detection training exercise at the Camp Lemonnier, Djibouti, post office, Sept. 13. The dogs are rewarded with their toys after successfully completing a task. Karo is the youngest member of the Camp Lemonnier K-9 unit.
