History of the Tosa Inu
Bred in Japan for hundreds of years, they developed this dog between 1868 and 1912 by crossing the Tosa with native Shikoku dogs and Kochi, which are a local Japanese breed. By the late eighteen hundreds, they developed today’s Tosa Inu. To increase their size, they crossed the best Japanese Tosas with imported European breeds such as the St. Bernard, Bull Terrier, Mastiff, and Great Dane. In Japan today they still consider the Tosa as a national treasure. Even in Japan, they are now a rare breed, which have just recently come to the United States. Some countries believe that they are a dangerous breed so they banned them. Because of their huge size, they require proper socialization, training, and handling by experienced dog owners or trainers.
