Sgt. Stubby died peacefully at home in 1926. He was honored with an obituary in the New York Times and received a posthumous Purple Heart for his combat injuries (the medal wasn't introduced until 1932).
The real Sgt. Stubby is preserved along with his coat and medals by the Smithsonian Institution and are on display in the National Museum of American History, Washington, DC.
Officially endorsed by the United States World War I Centennial Commission.
The first major computer-animated film based on a true story, as well as the fourth animated film of all time to be based on a true story, after Pocahontas (1995), Balto (1995), and Anastasia (1997).
The idea of an animated film was born while researching a documentary series for public television tied to the WWI centennial. When the story of Sgt. Stubby emerged, writer/director Richard Lanni realized the potential to reach an entirely different audience through animation.
