The Tosa, also known as Tosa Inu, is an imposing and powerful dog breed originating from Japan. It is famous for its impressive stature, strength, and calm demeanor. The Tosa was originally bred for dog fighting, a controversial practice that shaped its physical characteristics and temperament.
Physically, the Tosa is a large dog, with males typically reaching between 60 and 82 cm at the withers, and weighing between 50 and 80 kg. Females are slightly smaller. Its body is muscular and well-proportioned, with a broad and deep chest that attests to its power. The head is imposing with a wide and flat skull, a thick muzzle, and powerful jaws. The eyes of the Tosa are medium-sized, oval-shaped, usually expressing a calm and attentive expression.
The Tosa's coat is short, dense, and smooth, often in solid colors such as red, fawn, black, or brindle. Its skin is thick and loose, historically an advantage in fighting to reduce bite damage.
In terms of personality, the Tosa is generally calm, stoic, and dignified. It is known for its confidence and bravery, as well as its loyalty to its family. While it may be reserved with strangers, it is rarely aggressive without provocation. However, its potential for dominance requires early socialization and firm leadership in training.
Outside of its controversial past, the Tosa is often appreciated as a loyal and affectionate companion. It can be protective of its family and tends to coexist well with children if properly socialized. However, due to its size and strength, careful supervision is necessary when in the presence of other pets.
