American soldier J. Robert Conroy befriended a stray dog with a stumpy tail while training to fight overseas in WWI. They bonded so closely that Conroy smuggled him to Europe, where Stubby accompanied Conroy's regiment on the Western Front, lending both his superior olfactory senses and amiable temperament to the war effort.
