About The Breed

The Tosa exhibits a blend of patience, self-assuredness, and a spirited bravery. This breed is epitomized by its gentle calm and obedient nature all while maintaining an alert and composed presence. Originally cultivated for the rigors of combat they have now transitioned to roles as vigilant guardians. In the comfort of home Tosas show a subtle fondness for their families, yet they hold a reserved demeanor towards those unfamiliar to them. Naturally predisposed to be watchful Tosas are cautious around other canines and may display defensive reactions to those they perceive as threats. However, displaying aggressive behaviors towards humans is atypical for these dignified dogs. Their short and plush coat comes in a spectrum of hues, including fawn, red, apricot, black and brindle, often accented with white touches on their chest and paws. Tosas develop at a contemplative pace, with some not reaching their full magnificence until the age of four. Renowned for their impressive stature, Tosas are the most formidable among Japanese canine breeds and are affectionately known by a variety of names such as the Tosa Ken, Tosa Inu and the Japanese Mastiff, to name a few.

Although some canines may encounter health difficulties throughout their lifetime Tosas typically represent a robust breed with fewer afflictions. Engaging with a conscientious breeder can provide future Tosa owners with valuable knowledge and insight into any potential health issues that are known to affect this specific breed.

Health Assessment Recommendations from the Breed's National Association:

Health

Grooming

+
The Tosa's compact and plush fur is low-maintenance, making grooming a simple task. A sporadic brush-down is enough to keep their coat in good order. Additionally, an infrequent bath will ensure they remain fresh and presentable. It's important to regularly trim their sturdy quickly growing nails using a clipper or grinder to prevent any splitting or overgrowth. Regular ear inspections are also advised to prevent wax accumulation and potential infections. To promote dental health, routine teeth brushing is recommended.
Health

Exercise

+
Tosas still require physical activity to stay healthy and mentally engaged. Exercise opportunities might include romps in a securely fenced yard or leisurely strolls outdoors. Indoor play, such as chasing a ball across the floor or mastering new commands can also offer mental and physical workouts. Outdoor adventures, like trekking through nature or playing fetch are excellent for channeling their energy. Additionally, participating in canine sports such as agility, obedience or rally can be an enjoyable way to keep your Tosa fit and active.
Health

Training

+
Due to their innate eagerness to satisfy their owners Tosas thrive under training approaches that employ positive reinforcement. This method not only bolsters their natural inclination to comply but also fosters a strong trust-filled relationship between the dog and the trainer.
Health

Nutrition

+
A Tosa will flourish on a diet of high-quality canine nutrition whether it's through commercially available food or meals prepared at home with the guidance and endorsement of a vet. It's crucial to align their diet with their life stage, whether they're a pup, an adult, or in their senior years. Since some dogs may have a tendency to gain excess weight it's vital to be mindful of their caloric intake and keep a close eye on their physical condition.

Historiography

The intricate history of dog fighting in Japan extends back to the 14th century, with the island of Shikoku's native Shikoku Inu reigning supreme in the combat rings before the Western influence set in. The pivotal moment came with Commodore Perry's landing in Japan in 1854, sparking an era where Japanese dog enthusiasts started integrating foreign breeds with their local dogs. This led to the emergence of the Tosa as a crossbreed between the Shikoku-ken and imported Western fighting breeds. Named after its birthplace in the former Tosa Province, now known as Kochi Prefecture, the Tosa is often referred to as the Japanese Mastiff. This breed stands out for its valor and staunch performance in Japan's dogfighting circles.

Key contributors to the Tosa's lineage were Bulldogs (1872), Mastiffs (1874), German Pointers (1876), and Great Danes (1924), introduced sequentially to refine the breed characteristics. There are mentions of Saint Bernards and Bull Terriers joining the lineage, although the specifics of their integration are less clear. The attributes of endurance and combative prowess, prevalent among Mastiffs are evident in the Tosa's genetic makeup as a result of these crossbreedings.

In Japan, Tosas have a stature similar to that of Sumo wrestlers being celebrated and respected in a manner befitting their noble and athletic heritage. Meanwhile, in the United States the Tosa Ken has adapted to life as a loyal companion and a dedicated protector of the home.
