The Japanese Tosa is a strong, muscular dog with a loyal and protective


temperament. It makes an excellent home guardian and is an

agile athlete, especially for its size and weight. The same characteristics


that made the Tosa an excellent fighting dog have made

it a good choice as a home guardian and working dog.



Since the Tosa is a mastiff, it should


not be slight of build. The broad head


possesses a wrinkled brow, which


becomes more prominent when the


dog is alert.


As in most breeds, the female's head


is not as broad as the male's and


should appear more feminine. The


Tosa has a strong jaw and its teeth


form a scissors bite.







The dark eyes (sometimes lighter in puppies) show an expression of dignity


and loyalty. The rim of black around the eye absorbs sunlight and prevents


the reflection of the sun's rays into the eyes.

With its somewhat pendulous, thick, black lips, the Tosa is sometimes


mistaken for a hound breed at various stages of its life, but, as a mature dog,


no one should make this mistake.


The muzzle can be the same color as the dog's coat or can be black, with a


black nose. The ears are shaped in a "V" and are considered a "drop" ear.


The hair on the ears is the softest on the dog's body.

Another important physical characteristic that sets the Tosa apart from other


breeds is its dewlap. Again, males have a more prominent dewlap, and it


more closely resembles that of the Dogue de Bordeaux than the pendulous


dewlap of the Neapolitan Mastiff.

The coat is short, with various levels of coarseness. Color ranges from fawn


to red, black and brindle, with the fawn or red being the most preferred.


Slight white markings on the chest and paws are most acceptable for this





Any departure from the foregoing points should be considered as a fault and


the seriousness with which the fault should be regarded should be in exact


proportion to its degree.
