What were Tosa Inus bred for?
Tosa Inus were bred for dog fighting. While this practice isn’t completely outlawed in Japan, it is banned in at least five prefectures as increasing animal welfare standards and growing public opposition have led to less prominence and acceptance of Tosa Inu fighting compared to the past. Today, Tosa Inus are also beloved as loyal family members.
