Smoky was found in a foxhole by an American solider during the war and later sold to Cpl. Bill Wynne. She became a wartime sensation, backpacking through the New Guinea jungle and visiting injured soldiers to become one of the first therapy dogs.
Wynne found her exceptionally easy to train and she was soon aiding in the war effort, including an assignment to help string communication lines between outposts in the Philippines.
After the war, the pair traveled the country, visiting Hollywood and performing on local television shows.
