About This Breed
The Tosa Inu is Japan's largest dog breed, developed in the Tosa region (now Kochi Prefecture) as a fighting dog by crossing native Shikoku with Western breeds. Quiet, patient, and dignified, they are powerful yet surprisingly gentle.
Characteristics
Scores describe general breed tendencies, not an individual animal. A higher score means more of the named trait or need; it does not always mean better.
