Sergeant 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. He was the official mascot of the 102nd Infantry Regiment (United States), assigned to the 26th (Yankee) Division. Stubby 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 stories in major newspapers.
After returning home, Stubby became a celebrity – leading and marching in many parades across the country. He met Presidents Woodrow Wilson, Calvin Coolidge, and Warren G. Harding. In 1921 General John J. Pershing presented a gold medal from the Humane Education Society to Stubby, which was the subject of a famous photograph. Starting in 1921, he attended Georgetown University Law Center with Conroy, and became the Georgetown Hoyas' team mascot. He would be given the football at halftime and would nudge the ball around the field to the amusement of the fans. Stubby went on to perform in vaudeville shows! He earned $62.50 for three days of theatrical appearances, more than twice the weekly salary of the average American. For nearly a decade after the war until his death in 1926, Stubby was the most famous animal in the United States.
Upon his death in 1926, Stubby received an obituary in the New York Times. The obituary was half a page, which was much longer than the obituaries of many notable people of the time period.
