Sergeant Stubby (1916 or 1917 – March 16, 1926) was a dog who was the official mascot of the 102nd Infantry Regiment (United States), assigned to the 26th (Yankee) Division. He served for 18 months and participated in seventeen battles on the Western Front. He saved his regiment from surprise mustard gas attacks, found and comforted the wounded, and once caught a German soldier by the seat of his pants, holding him there until American soldiers found him. Back home, his exploits were front page news in major newspapers.
Stubby has been called the most decorated war dog of World War I and the only dog to be nominated for rank and then promoted to sergeant through combat, a claim having no official documentary evidence, but recognized in connection with an exhibition at the Smithsonian Institution.
Sgt. Stubby is the subject of an upcoming animated film, scheduled for release in April 2018.
