Character Tosa Inu

Although Tosa Inu dogs are decried as “fighting machines,” they are calm and peaceful animals. According to the FCI, the Tosa Inu is one of the mastiff-like dogs. With the Tosa Inu, the combination of the imposing figure and the calm nature is particularly striking.
The Tosa has a very cool, almost condescending charisma. Males should have a height of 60 centimeters.

Bitches, on the other hand, should not be less than 55 centimeters. With a proud weight of 50 to 70 kilograms, it is a very large and muscular dog. As a result, he demands a lot of strength from his master.
The Tosa Inu’s fur is hard, short and dense. Apricot, red, fawn, black and brindle are recognized as coat colors.

Discreet markings on the chest and feet are permitted. Fearful, shy or aggressive dogs are excluded from breeding.
The Tosa Inu has a balanced personality . Hardly anything fazes him. True to the saying “the quietest are the bravest”.

He is oriented towards his family members. He is always loyal to his master.
The Tosa is neutrally repellent towards strangers. However, the dog is easily petted by strangers. If he likes someone, then that friendship will last a lifetime.

He comes alone to get his cuddles.
His nature is defined in the standard: ” Determined by patience, composure, fearlessness and courage. This very strong dog needs a master with dog experience and sovereign composure. The Tosa Inu is therefore not recommended as a beginner dog.
The Tosa is good-natured , fond of children and people-oriented .

However, the dog is not always compatible with other four-legged friends. He tends to be dominating. The dog is confident and calm, but always wide awake. The Tosa is a real stubborn one.
As with all other breeds, training of the Tosa Inus should begin as early as possible .

Consistency is particularly important. The dog should be shown exactly what it can and cannot do. Yelling is useless, you should bring an unmistakable authority. Therefore, children in particular should not be left unsupervised with the dog.

Diet Tosa Inu

To prevent the dreaded hip dysplasia , you should always keep an eye on your four-legged friend’s food. Puppies need a fairly high-energy food. The energy density of the feed should be slowly reduced after six months. This avoids growing too quickly. Because joint problems often arise when the dogs grow very quickly and the bones cannot keep up properly.

Otherwise, the Tosa Inu has no special requirements for its food. He likes meat and fish equally. He likes to eat them raw, but also cooked. He accepts dry and wet food.
However, you should note that the breed puts on fat quickly.

Especially if obesity is already known in breeding, you should pay attention to the right amount of food. You should also avoid eating too many treats. You can consult a veterinarian to find out exactly what and how much to put in the food bowl. A nutritionist specifically for dogs can also provide advice.
Not only the ration of the feed is important.

The ingredients and the composition also play an important role. The need for minerals depends on the individual criteria of your dog. These include age, activity level, weight and housing conditions.
If your Tosa Inu often sleeps outside in cold temperatures, its energy requirements will also increase. Demand increases by around 30 percent.

Under normal conditions, a full-grown male dog with an average level of exercise needs around 1.5 kilograms of meat and almost 500 grams of vegetables.
It is also important that the dog always has fresh drinking water freely available. Because the dog drools a lot because of the big lips. Especially when eating, long threads often hang out of its mouth. Therefore, his water bowl should be rinsed out often and filled with clean water.

Otherwise bacteria can easily settle in the water.


In contrast to consistent training, the four-legged friend makes few demands on care. Regular brushing is absolutely sufficient for the Tosa with its short coat. The Tosa Inu is also quite robust in terms of health . Disease patterns typical of the breed are hardly known in the dog.
Hip dysplasia is the only problem.

Dogs should not be physically overloaded, especially during the growth phase. Long running sessions and frequent stair climbing should be avoided at all costs during this time.
A soft lying surface is also important for the Tosa. The strong dog tends to develop calluses quickly if it lies on hard ground for a long time. Therefore, you should invest in a good dog bed .

The Tosa is quite undemanding in terms of external conditions. However , a flat is not suitable for keeping them. He likes a big house with a garden best . The four-legged friend likes to be outdoors, but is not a kennel dog.
The Tosa Inu is basically very easy to care for.

With a knowledgeable owner, he can be a family pet and friend of children. Dogs especially love children. But he does not always accept other animals in the household.
But you have to consider one fact before you buy it. The Tosa is considered a dangerous dog in some states.

In several countries, it is also one of the dogs that are not allowed to be kept and imported. You shouldn’t go on holiday with Tosa to the Netherlands . There is a risk of confiscation and in some cases even euthanasia.
The Tosa Inu understands people very well. He also likes to follow people.

This happens on the basis of mutual respect and recognition. If you take this to heart, you will be rewarded with a wonderful friendship between dog and human.


The Tosa Inu is originally from Japan . It is the largest dog breed there. The dog was originally a docile Japanese fighting dog. Fighting dog, however, means almost the opposite of the image of the fighting dog in Germany. The dog fights in Japan are modeled on the fights of sumo wrestlers.

The battles have been fought since the 14th century.
The fight is a ritualized contest . In addition to physical strength, mental strength is particularly important. The dogs must not hurt each other in the fight. The dogs are meant to push each other down and impress.

Special judges judge the mental strength of the dogs.
These dogs are not allowed to show aggression. They are not even allowed to growl. Growling means immediate disqualification. Therefore, the Tosa Inu is also called “Sumo Inu”.

The dog breed is highly revered in Japan. It is estimated that around 10,000 Tosa Inus are kept there. In Europe, the Tosa is also known as the “Japanese Mastiff”.
Larger incidents against humans are not yet known. The dogs have a very high stimulus threshold.

The dog is very calm, especially towards people. He’s not easily provoked. A Tosa Inu is just too cool to simply lure him out of his reserve.
The Tosa as we know it today is rather young. The traditional Tosa Inu “Shikoku-Ken” should be improved by European breeds.

According to the standard, Mastiffs, Bulldogs, Great Danes and German Pointers were crossed.
Only in 1964 was the Tosa recognized by the “Fédération Cynologique Internationale”. In Germany, the strong dog is a rarity. The first purebred dogs came to Germany around 1970. Nevertheless, it is still one of the rarest breeds at all.

Not even a handful of Tosa Inu breeders are officially registered in the VDH.

Tosa Inu Accessories

The strong Tosa Inu loves to do sports. Due to its stately size alone, it needs a lot of exercise. Various sports are suitable for this. The Tosa Inu can already ride a bike at the age of one and a half years . He also likes to accompany you when jogging .

If the spout is smaller, he doesn’t blame you. You should still note that the Tosa likes to do sports, but is not enduring. Very active dog owners who walk long distances with the dog every day will not have fun with the muscle man. The Tosa appreciates being distracted from everyday life with suitable toys .
Because of its strength, the dog needs a strong leash .

The dog collar should also be stable. Special leashes and collars are available in almost every good specialist shop. Otherwise, the Tosa Inu does not require any special accessories.
