Origin and History
The origin of the Tosa was on the island of Shikoku at the place called Tosa Wan in Japan. Its written record was found which proves that it has been in Japan for over a thousand years. It was bred to use for dogfighting in the ring.
Tosa is believed to be developed by crossing western breeds like German Pointer, Bull Dogs, Mastiff, and Great Danes to increase its strength, power, and size. Tosa becomes renowned for its fighting ability.
Tosa is still treated with great honor in Japan as a fighting dog. However, in the United States, it is kept as a guarding dog and family companion.
The United Kennel Club recognized Tosa in 1998 under guardian breed. The American Kennel Club has kept this breed in the Foundation Stock Service since 1997 (as of April 2019).
