Tosa

Posted in Working Group

A Breed Standard is the guideline which describes the ideal characteristics, temperament and appearance of a breed and ensures that the breed is fit for function with soundness essential.  Breeders and judges should at all times be mindful of features which could be detrimental in any way to the health, welfare or soundness of this breed.

UTILIZATION: Formerly fighting dog, nowadays watchdog.

BRIEF HISTORICAL SUMMARY
Japan has a long history of dog fighting, beginning in the 14th century. With such a history in the background, this breed was produced as hybrid of Shikoku-ken and Western breeds. Named after the area where they were bred, these dogs are sometimes called ‘Japanese Mastiffs’. The Western dogs used for creating the breed were Bulldogs (1872), Mastiffs (1874), German Pointers (1876) and Great Danes (1924) all of which were used to improve the breed by sequential mating. According to some accounts, St. Bernards and Bull Terriers were also involved but it is not known in which years they were used. The Tosa’s established features of stamina and the fighting instinct typically found in Mastiffs may be attributed to the involvement of such breeds.
