8. Dogo Argentino
The Great Dane breed appeared in Argentina in 1928. She was taken out of the disappeared fighting dog Cordoba, which was crossed with various other breeds, including the Danish Great Dane, the Great Dane and the Irish Wolfhound. The breeder Antonio Martinez brought this dog to hunt such a dangerous beast as a cougar. Although this breed is no longer used for its intended purpose, it is still a fighting dog. Weighing up to 50 kilograms, Argentinean dogs are very strong and somewhat resemble pit bulls. The breed is banned in at least 10 countries, including Australia, New Zealand and Portugal.
