For the next two years, Smoky back-packed through the rest of the war and accompanied Wynne on combat flights in the Pacific. She faced adverse circumstances, living in the New Guinea jungle and Rock Islands, suffering the primitive conditions of tents in equatorial heat and humidity. Throughout her service, Smoky slept in Wynne's tent on a blanket made from a green felt card table cover; she shared Wynne's C-rations and an occasional can of Spam. Unlike the "official" war dogs of World War II, Smoky had access to neither veterinary medicine nor a balanced diet formulated especially for dogs. Despite this, Smoky was never ill. She even ran on coral for four months without developing any of the paw ailments that plagued some war dogs.
