Sergeant Stubby died on March 16, 1926, as a hero, yet today, many people do not know who he is. Sergeant Stubby is the most decorated dog in military history, and the only dog to have been promoted during battle. He fought for 18 months in the trenches for France during WW1 for 17 battles. Stubby warned his fellow soldiers of gas attacks, located wounded soldiers in No Man's Land, and listened for oncoming artillery rounds. He was also responsible for the capture of a German spy at Argonne. After his time in the war, Stubby met Woodrow Wilson, Calvin Coolidge, and Warren G. Harding. He was, also, made a life member of the American Legion, the Red Cross, and the YMCA.

Jack Brutus was another famous military dog. Although, he did not get nearly the publicity as Stubby, Jack Brutus was the the official mascot of Company K, First Connecticut Volunteer Infantry. He was much larger than Stubby and was never smuggled anywhere with his troops (as Stubby had been). Jack Brutus died in 1898 of spinal troubles and constipation. He was much larger than the famous Sergeant Stubby but was definitely a pit bull type dog.
