The Canton Bulldogs were a professional American football team, based in Canton, Ohio. They played in the Ohio League from 1903 to 1906 and 1911 to 1919, and the American Professional Football Association (later renamed the National Football League (NFL) in 1922), from 1920 to 1923 and again from 1925 to 1926. The Bulldogs would go on to win the 1916, 1917 and 1919 Ohio League championships. They were the NFL champions in 1922 and 1923. In 1921–1923, the Bulldogs played 25 straight games without a defeat (including 3 ties), which as of 2019 remains an NFL record. As a result of the Bulldogs' early success along with the league being founded in the city, the Pro Football Hall of Fame is located in Canton. Jim Thorpe, the Olympian and renowned all-around athlete, was Canton's most-recognized player in the pre-NFL era.
