The Tosa is a large-sized breed. Males typically weigh between 36 and 61 kg when fully grown, while females weigh 36 to 61 kg. With an average lifespan of 10 to 12 years, the Tosa is a moderately long-lived breed.
The Tosa is a powerful and dignified breed with a calm, steady temperament. They are devoted to their families and can be gentle giants at home. They require an experienced owner who understands large breed needs. Proper training and socialisation from puppyhood are essential for a well-adjusted adult dog.
Tosa dogs are active and need at least 1-2 hours of vigorous daily exercise. Long walks, hiking, and off-lead running in safe areas are ideal. They have good stamina and enjoy outdoor adventures. Puppies should have controlled exercise to protect growing joints. Mental stimulation through training is also essential.
As a large breed, Tosa dogs may be prone to hip and elbow dysplasia, bloat (gastric dilatation-volvulus), and joint problems. Large breeds can also be susceptible to certain cancers and heart conditions. Feeding a large-breed-specific diet during growth helps prevent skeletal issues. Regular veterinary check-ups are essential for early detection of health problems.
Tosa dogs need regular grooming including weekly brushing to manage their coat and reduce shedding. Bathing can be challenging due to their size — a walk-in shower or professional groomer may be helpful. Regular nail trimming is important. Check ears regularly, especially if they are floppy, as moisture can lead to infections.
