Known also as the Japanese Mastiff, the Tosa hails from Japan. In fact, these dogs come from the Tosa Province, so the dog was named after the region where they were bred.
It is why they are sometimes referred to as Japanese Mastiffs. The Tosa is a rare dog breed and unfortunately, the dog is still used in Japan for dogfighting.
The breed was developed in the 2nd half of the 19th century, with a number of dog breeds being involved to bring about a more powerful, braver dog.
The Tibetan Mastiff is still considered to be a primitive breed originating in Tibet centuries ago. The breed was developed to guard property and livestock. They still do this as well as being a much loved family dog and a show dog as well. There is very little history that is documented for the breed prior to the 19th century.
Believed to be centuries old with ancestors who are mastiff like dogs that developed into two different types of Tibetan Mastiffs. These types are the Tsang-Khyi and the Do-Khyi. The Tsang Khyi were guardians for Tibetan monks, while the Tsang-Khyi guarded flocks for nomadic shepherds and in villages.
The first Tibetan Mastiff was imported in 1847 to England and presented as a gift to Wueen Victoria, from India’s Viceroy. By 1873 there was an English Kennel Club and the breed was labeled a large dog from Tibet and entered into the EKC Stud Book.
The next year the future King Edward VII, brought another two Tibetan Mastiffs to the United Kingdom to show in 1875. The first breed club began in 1931. The world wars interfered and no new dogs were imported to England until 1976. Two dogs were given to the President of the United States in the late 1950’sbut were not bred and it wasn’t until 1970 that any more were imported. The US Tibetan Mastiff Club was not founded until 1974 and they were first entered in a National Specialty show in 1979.
In 2007 the AKC recognized the breed as a working dog since 2007. It’s hard to find a purebred Tibetan Mastiff in Tibet anymore.
The Tosa is a large dog, but their sizes vary, and in fact, because of their fighting, they are actually divided into light-, middleweight and heavyweight classes.
Generally, you can say that these dogs weigh in the region of 54 to 90kg and they stand in height at between 62 to 82cm. The head is large, the jaws powerful, the eyes dark brown in color, the ears small, high set and floppy.
The neck is broad wit a dewlap and the tail is long, thick and tapering to a point. The coat is short and thick and is most times a rich caramel color, fawn tan, black or brindle. The dog often has a black mask.
The Tosa is a fairly quiet dog, courageous and fearless. He is going to need a strong, consistent owner who shows leadership with him. Training and socialization will be imperative for this dog.
When he has been properly reared and trained, he makes a good pet, able to get on with members of the family. He takes his role as protector and guardian seriously.
Both types of Mastiffs can be present in the same litter, so that both larger and smaller pups are present. Both types are well-muscled and structured. Today’s dogs being developed in China and the West are much larger than the previous ones. These dogs would be less useful to the nomads and cost too much to feed. Today’s dog is very large with a large head and a long double coat. This coat can be black, brown, gold, and blue, with or without tan markings. There are now a few white Tibetan Mastiffs being bread.
The breed standard for the Mastiff is different in the West than in the East. In the East the breed is broken into two categories – the Lion Head and the Tiger head.
The Tosa isn’t recommended for first-time dog owners, as in the wrong hands, they can become aggressive. Care has to be taken around children too especially undisciplined ones.

The Tosa is a formidable looking molossoid, but even so, this big, calm dog can succumb to illness. Some of these diseases you need to be looking out for include bloat,hip dyslasia and eye conditions.
Bloat for this dog can be life-threatening, and can often be because the dog is too hungry and he gobbles up his food quickly. Bloat is when gas can't escape, the stomach swells and twists – very dangerous. Rather give your dog two smaller meals – one in the morning and one in the evening, or even give several smaller portions throughout the day.
To help with eliminating health issues always choose a reputable Tosa breeder. You’re not likely to find one of these dogs in a dog shelter.
Though considered a primitive dog and isolated for several centuries, so they should not have as many genetic or inherited conditions as other dogs with more cross and in-breeding. These are the potential health issues they might develop:
Elbow and Hip dysplasia – can lead to lameness and arthritis.
OCD Osteochondrois Dissecans – this is also an orthopedic condition when the soft tissue growth is abnormal in the joints. It is painful and the joint is stiff. Don’t breed a dog that has this condition.
Panosteitis – Canine growing pains. Inflammation of the long bones in large dogs as they grow. They will eventually out grow it. Pain can be managed through medication.
Autoimmune Hypothyroidism – Hormone deficiency leading to flaky skin, weight gain and lack of energy. Can be managed through medication.
Canine Inherited Demyelinative Neuropathy – If your Tibetan Mastiff is going to have this condition, they will have it by six weeks of age. Weakness in the hind legs leading to paralysis.
Bloat – deadly if not treated immediately and related to dietary habits.
These large, strong dogs do well on good quality food. If you opt to buy him commercially manufactured food, make sure it is the top quality one free of unwholesome ingredients such as preservatives, colorants and useless fillers.
Invest in the best quality ones that have nutritious minerals and vitamins. Try and give your dog some home-prepared food too – boiled chicken, brown rice or pasta, spinach, sweet-potatoes and carrots.
Never feed your dog things such as chocolates, peanuts, crisps, grapes, onion and food with spicy flavorings. This will just ensure digestive problems and having to get your dog to the vet.
The Tosa’s short coat isn’t going to require too much attention. A good brush twice a week will keep it free from loose hair and keep its shine and gleam. It’s why the dog is looked upon as being low maintenance.
Beyond that, he will need to have his nails trimmed. When brushing him, check him over for parasites – ticks and fleas, check for unusual lumps and look inside his ears for signs of redness.
These dogs are calm and fairly low-energy. Nonetheless, to maintain good health, he will need to be exercised. Ball games outside are always a good idea as well as nice long walks. Hikes into the countryside will be wonderful for this big dog.
Don’t feed the puppy too much protein as you want to prevent Panosteitis and growing too quickly. Do not overfeed. Feed 4-5 cups of high quality large breed puppy food in 3-4 meals day.
4 to 6 or more cups of a high-quality dog food daily, divided into two meals. To avoid bloat do not feed before or after vigorous exercise.
Calm and laid back when inside.
They need 20-30 minutes of vigorous exercise and play daily. They prefer to play with other large dogs.
