While in a war zone, a military working dog (MWD) and its handler live together, eat together, play together, sleep together, and risk their lives for each other every day. The dogs work with handlers in every branch of the US military. They guard military bases, sniff out concealed explosives and other weapons, and alert their handlers to hidden enemies. Learn how the military selects these special dogs and trains them for the many tasks they perform while on duty. Meet Rex, Clipper, Maci, Iva, Ikar, and other MWDs who have served the US military in conflicts around the world.
