Man's best friend goes to war. Chuck and Ajax are partners, and they're good at their job. Chuck leads Ajax through the jungles of Vietnam, and Ajax sniffs out hidden, deadly traps before they can hurt US soldiers. The war is almost over now, and the Army is grateful for Chuck's service. They want to give him a medal. But their plans for Ajax are less noble. Suddenly, Chuck is forced to answer two impossible questions: Is his loyalty to Ajax or to the US Army? And just how far is he willing to go to protect his partner? Dog Tags is a series of stand-alone books, each exploring the bond between soldier and dog in times of war.
