This breed is a variant of Tosa inu
The tosa was developed in Japan during the late 1800s and early 1900s to create a formidable competitor in dog fighting rings. It was developed by breeding mastiffs, great Danes, St. Bernards, bulldogs and bull terriers with native Japanese fighting dogs, the Kochi. The result was a silent combatant that could fight relentlessly. Today, dog fighting is illegal in Japan, Europe and North America. The Tosa is currently registered in the American Kennel Club’s Foundation Stock Service program, which is the first step toward gaining official breed recognition in the future.

Tosas do not require much grooming. Going over the dog once a week with a grooming mitt will remove dead hairs and redistribute the natural oils to maintain healthy skin and the smooth coat’s glossy sheen. Inspect the tosa’s ears weekly for debris. Clean them if necessary and keep them dry to reduce the chances of ear infections. Reduce plaque buildup and periodontal disease by brushing the teeth three times a week.
