Breed Profile:

The Tosa Inu (also known as the Tosa-Ken and Tosa-Token) originated in Japan in the mid-19th century where he was developed as a silent, heroic dog fighter with the ability to battle to the death without complaint. Sometimes referred to as "the canine equivalent of Sumo wrestlers", in their homeland, Tosas are treated with great honour and ceremony. In recent years, some have been exported to North America and Europe as companion and guard dogs. The breed was produced using the Shikoku-ken and combining several other breeds, including the Bulldog, Mastiff, German Pointer, and Great Dane. The breed is the largest of all the Japanese breeds and is also sometimes called the Japanese Fighting Dog and the Japanese Mastiff.

The Tosa is patient, composed, bold and courageous. Very protective of his home and family, the Tosa is generally considered excellent with children, however, due to his large size, proper supervision should be maintained at all times. He is powerful, robust and agile, generally quiet and obedient, with a calm but guarded disposition. The Tosa can be aggressive to other dogs but aggressive behaviour toward humans is uncharacteristic of the breed. It is strongly recommended that anyone considering a Tosa should have experience with large breed dogs.

The Tosa Inu gives an overall appearance of a massive, large-boned and athletic dog. He has a short, smooth coat with the preferred colour being a deep, solid red. Other colours include other shades of red, including fawn; a combination of red and black brindling; dull black; brown; black with red markings; and pied. He may also have a black mask and black tipped hairs.

Health Issues

If you are considering the adoption of a Tosa Inu puppy, or any breed, it is very important to be selective in choosing a responsible and reputable breeder. Ensure that the prospective puppy's parents have all health clearances. Breeding of any dog should not be done until after they have been proven to be free of evidence of significant hereditary diseases. (For more information on selecting a breeder, see the articles on the main Breed Listing and Breeders page.)
