Sergeant Stubby (1916 – March 16, 1926) was a dog and the unofficial mascot of the 102nd Infantry Regiment (United States) and was assigned to the 26th (Yankee) Division in World War I. He served for 18 months and participated in 17 battles on the Western Front. He saved his regiment from surprise mustard gas attacks, found and comforted the wounded, and allegedly once caught a German soldier by the seat of his pants, holding him there until American soldiers found him. His actions were well-documented in contemporary American newspapers. Stubby has been called the most decorated war dog of the Great War and the only dog to be nominated and promoted to sergeant through combat. Stubby's remains are in the Smithsonian Institution. Stubby is the subject of a 2018 animated film. Early life Stubby was described in contemporaneous news items as a Boston Terrier or "American bull terrier" mutt. Describing him as a dog of "uncertain breed," Ann Bausum wrote that: "The brindle-patterned pup probably owed at least some of his parentage to the evolving family of Boston Terriers, a breed so new that even its name was in flux: Boston Round Heads, American... and Boston Bull Terriers." Stubby was found wandering the grounds of the Yale University campus in New Haven, Connecticut in July 1917, while members of the 102nd Infantry were training. He hung around as the men drilled and one soldier in particular, Corporal James Robert Conroy (1892-1987), developed a fondness for him. When it came time for the outfit to ship out, Conroy hid Stubby on board the troop ship. As they were getting off the ship in France, he hid Stubby under his overcoat without detection. Upon discovery by Conroy's commanding officer, Stubby saluted him as he had been trained to in camp, and the commanding officer allowed the dog to stay on board. Military service Stubby served with the 102nd Infantry Regiment in the trenches in France for 18 months and participated in four offensives and 17 battles. He entered combat on February 5, 1918, at Chemin des Dames, north of Soissons, and was under constant fire, day and night for over a month. In April 1918, during a raid to take Seicheprey, Stubby was wounded in the foreleg by retreating Germans throwing hand grenades. He was sent to the rear for convalescence and, as he had done on the front, improved morale.
