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.
