The Japanese Tosa is also banned in the UK. It too was bred specifically for blood sports, but came from Asia. Japanese rules meant dogs weren't allowed to make any noise in the pit, so the Tosa is said to have been able to fight completely silently. The other two illegal breeds, the Dogo Argentino and Fila Braziliero, both came from South America.
The Presa Canario is banned from ownership, import and breeding in both Australia and New Zealand, as the authorities of these countries consider the breed to both have a natural propensity for aggression, and be large enough to inflict serious injury or even fatal wounds upon people.
The Fila Brasileiro is banned or restricted in a number of countries, including the United Kingdom, Australia, New Zealand, Norway, Denmark, and others. In the United States, insurance companies may cancel your homeowner's policy. In this day and age, the legal liabilities of owning a giant breed that looks intimidating should be considered.
The Dogo Argentino is banned or has ownership restrictions in certain countries including Ukraine, Denmark, Iceland, Fiji, Australia, New Zealand, Singapore and the Cayman Islands. In the United Kingdom, under the Dangerous Dogs Act 1991, it is illegal to own a Dogo Argentino without lawful authority.
The term Bandog (also known as Bandogge) is believed to have originated in the Middle Ages in England. Johannes Caius published a book in Latin in 1570, translated into English in 1576 by Abraham Fleming under the title, Of Englishe Dogges, in which he described the Bandog as a vast, stubborn, eager dog of heavy body.
