National Geographic's June issue cover story is called ”Hero Dogs, A Soldier's Best Friend.” Layka, the proud dog featured on the cover, was recently recognized by an Air Force unit for her heroics in Afghanistan. The 3-year-old Belgian Malinois was dispatched to inspect a building for explosives and search for enemy combatants. She was ambushed, receiving several gunshot wounds to the abdomen and right front leg. Despite being gravely wounded, she protected the lives of her team by attacking and subduing the assailant. Luckily, Layka survived, but her injuries were so severe that doctors had to amputate one of her legs.
