Sgt. Kelly Carmody of Fayetteville, N.C., cuddles the earless puppy while on patrol.

Unfortunately, dog fighting is a popular sport in Afghanistan, especially during the winter months. To prepare them for a life of dog fighting, puppies often have their ear flaps removed so that other dogs won't latch onto them during a fight.
