The Japanese Tosa was originally bred for dog fighting and is considered a rare and highly powerful breed. Unlike many dog breeds, the Tosa Inu was developed to fight silently, making them intimidating and unpredictable in combat situations.
Because of their size and strength, Tosa Inus are banned in Denmark, Norway, Iceland, and the UK. Even in Japan, where they originate, they are heavily regulated. Although they can be loyal and protective companions, their naturally dominant nature makes them unsuitable for first-time owners.
Why They’re Banned: Large size, history in dog fighting, and unpredictable behavior. Where They’re Banned: UK, Denmark, Norway, Iceland, and some parts of Europe.
