During World War I, a patriotic stray dog wandered onto the 102nd Infantry, Yankee Division training area. Usually dogs were not allowed in the regiment, but this pup, named Stubby for his short tail, boosted morale so much that they allowed him to stay. There, he learned the drills, bugle calls, and how to salute! When it was time to deploy, Private J. Robert Conroy smuggled their new solider onto the ship heading toward France. When his presence was discovered, Stubby quickly won him over with his cutie salute.
What's even more remarkable about this pup is that the was allowed to join soldiers on the front line, eventually serving in 17 battles. He had a keen knack for locating his wounded comrades, warning about an enemy gas strike, and even attacking a German soldier attempting to map out the layout of Allied trenches. This pup was rightfully promoted to Sergeant Stubby and became a lifetime member of the American Legion, won the gold hero dog's medal, and later became one of Georgetown University's earliest mascots.
