The Tosa Inu is a brave, fearless and bold dog. The Tosa Inu is quietly affectionate with its own family. This breed is exceptionally quiet, calm and patient. It has been bred to be a very quiet dog because Japanese dog-fighting rules require the dogs to fight silently. This dog is highly intelligent and doesn’t need repetitious training, but does require an equable, consistent, friendly approach.

It responds best to positive-enforced training methods because of an inherent desire to please its owner. The owner must learn to control this dog, as it is too large and strong to be unmannerly. This dog requires a strong and experienced owner capable of dealing with a large, powerful animal.

With proper training and control, the Tosa Inu can be a good family companion. The Tosa Inu shows remarkable acceptance of children and will not snap or bite from fear or pain. However, due to its size, it should not be left with children unsupervised.

They make excellent home and family protectors and companions. The sheer size of this dog and its deep bark are effective deterrents. It is reserved with strangers, but will accept newcomers if properly introduced. It tends to be fairly dog aggressive, but it gets along with other dogs and pets only when raised with them from puppyhood.


Tosa Inu colors

Solid red, though black, yellow, black & tan, fawn, brindle and multi-colored is also permissible.

Health Issues

Avoid vigorous exercise right after the dog has eaten a big meal.  Ask about bloat in the lines. Bloat can be a major problem in these large dogs. To minimize the risk of your Tosa developing any hereditary health issues, you should buy a Tosa Inu dog from a reputable breeder.

Living Environment

Although it takes up a relatively large space, the Tosa will be fine in an apartment as long as it gets regular exercise and outdoor exposures in even a small yard. When placed in a kennel, it will become unhappy, as it loves to be close to its humans.
