Sergeant Stubby at your serviceStubby sporting a blanket bedecked with medals made for him by the women of a French town he helped liberate during World War I.(more)Sergeant Stubby was a stray dog whose heroic service during World War I (1914–18) saved lives and even led to the capture of a German spy. He was the unofficial mascot for the 102nd Infantry, 26th “Yankee” Division, and is the first dog to be promoted to the rank of sergeant in the U.S. Army.

　　When the 102nd Infantry was training for battle on the grounds of Yale University in 1917, a stray dog made friends with members of the company. Pvt. J. Robert Conroy developed a bond with the dog, and he and other soldiers named the dog “Stubby.” Stubby’s breed was unknown, but he had a distinctive tiger-striped coat.

　　The dog became the unofficial mascot of the 102nd Infantry at Yale, though dogs were not allowed in the camp, a rule that was overlooked because Stubby was good for morale. He even learned to salute by raising his right paw toward his face. When the soldiers shipped out for France to fight in World War I, Conroy smuggled the dog aboard the ship, and Stubby soon befriended the other troops.

　　Serving on the front lines Stubby’s saluting trick came in handy when he arrived in France along with Conroy and the other infantry members. Stubby saluted Conroy’s commanding officer, winning a place in his heart and, as it would turn out, a trip to the front lines as the 102nd’s mascot.

　　Stubby soon moved beyond his role as mascot to become an important asset to the troops in battle. He survived being wounded from exposure to mustard gas, recovering in a field hospital. After that exposure, Stubby was able to detect even small amounts of poisonous gas. When his division was under a gas attack, Stubby immediately recognized the smell and ran through the trenches, barking to alert everyone, and saving many soldiers from serious harm.

　　Stubby’s battlefield skills extended beyond gas detection. During the 17 battles he was involved in during his 18 months of service, he also located wounded men lying in fields between the trenches. His barks alerted searchers who then brought the wounded to safety.

Stubby was on his usual guard duty and recognized that the German did not belong in the camp; he ran after the spy, biting his legs as he tried to escape, thereby allowing Stubby’s human comrades to capture him. For his heroic efforts, Stubby was promoted to the rank of sergeant, the first dog to be promoted to the position.

　　In April 1918 Stubby’s unit was under attack during a battle near the German-occupied town of Seicheprey, France. Stubby was wounded in his chest and leg by shrapnel. During his treatment at a Red Cross hospital, he doubled as a therapy dog, visiting recovering soldiers to lift their spirits. He later returned to the battlefield and was involved in the Allies’ liberation of the French town Chateau-Thierry. The women of the town made Stubby a blanket and medals to thank him for his bravery.

　　Postwar life After the war Stubby became a celebrity, leading U.S. troops in a parade and meeting with U.S. Presidents Woodrow Wilson, Warren G. Harding, and Calvin Coolidge. He was awarded many medals for his heroism, including a medal from the Humane Society that was presented to him by Gen. John Pershing.

　　From New York Times obituaryAfter armistice Stubby spent his time congratulating and being congratulated. Traversing the streets of Paris, he was recognized by hundreds of French, English, Australian and American soldiers. And then on Christmas Day … he met President Wilson. Stubby the dog to whom rank insignia made no difference, offered his paw.

　　Stubby lives on The mascot of the Georgetown Hoyas was inspired by Sergeant Stubby who lived on campus while his owner attended law school after World War I.(more)During this time Stubby continued to live with Conroy while he attended law school at Georgetown University in Washington, D.C. There, Stubby became the school’s mascot. Stubby died on March 16, 1926, at about the age of 10, and he was memorialized in written obituaries in The New York Times and The Washington Post.

　　Sergeant Stubby’s remains were preserved and are on display at the Smithsonian National Museum of American History. His story was featured in a children’s book, Sergeant Stubby: How a Stray Dog and His Best Friend Helped Win World War I and Stole the Heart of a Nation (2014), written by Ann Bausum, and in 2018 he was the subject of an animated documentary titled Sgt. Stubby: An American Hero, directed by Richard Lanni.
