The Tosa Inu temperament is typically thought to be aggressive, but this description doesn’t cover the whole story. These massive dogs have a soft, laid back side that makes them a lovable family pet in the right hands.
Unfortunately, many times the Tosa Inu ends up with owners who are incapable of handling their temperament. When they fall into the hands of a first-time or abusive owner; someone who doesn’t offer them a stable environment, this can cause them to give into their more aggressive instincts.
With this in mind, it’s imperative that you evaluate whether or not you’d be a suitable parent for a Tosa Inu.
It’s going to take an experience, patient owner to successfully transition these dogs into suitable pets. If that’s not you, it’s best you move onto another breed.
The Tosa Inu Temperament & Personality
As we go over the following traits, one thing will become abundantly apparent; these dogs aren’t a match for a first-time owner. In some cases, a Tosa Inu temperament might not even mesh well with an experienced owner either.
The first thing you should know about Tosas or the Japanese Mastiff is
As you can imagine, this willingness to attack threats could be a problematic issue. It also doesn’t help that these dogs have a distrust of people and animals outside their families. If not properly trained, it’s not uncommon for them to act aggressively toward other dogs.
But if these dogs have a strong, authoritative owner, this fearless can become useful in desirable behaviors. For example, these dogs are always up for new things and experiences.
It also helps them become incredibly useful watchdogs with their willingness to risk their well-being for their owners. Honestly, there isn’t a better watchdog than a Tosa Inu; intruders don’t stand a chance.
But as mentioned previously, this fearlessness triggers their more aggressive instincts. It makes them more prone to challenging other dogs and become overly confrontational. Given their massive size and strength, this could result in an experience no dog owner wants.
If you get a Tosa Inu, their dog aggressive traits are something you must be incredibly mindful about. In fact, most experts agree that these dogs aren’t well-suited for suburban life because of this quality.
And if you do live in a suburb with a Tosa Inu, these dogs will bark at people walking their dogs; it can be a migraine inducing experience as their barking is very loud. You’ll also have to invest in higher fences, which will ensure your massive dog doesn’t escape.
However, you can train dog aggressiveness out of a Tosa Inu. It just becomes increasingly more difficult to do as they grow and their stubbornness rears its ugly head. As a result, starting their training at the soonest possible time is a must.
We also must note that keeping a Tosa Inu in the same house with other animals isn’t a good idea. The most ideal situation would instead be with an experience dog owner with absolutely no other pets around; this situation will make sure the Tosa has your full attention.
Due to its alpha personality, these dogs are more independent than other breeds. It also results in them being incredibly stubborn; they like to do their own thing and often will ignore an owner who isn’t commanding enough.
It’s something that can become somewhat problematic in certain situations. For instance, you’re
It might be a funny thing to think about right now as you’re reading this article. But it’s something you’ll need to take into account before getting one of these dogs. In other words, think about whether or not you have the wherewithal to successful control a dog of this size.
If you don’t and end up getting one, you become an accident waiting to happen. And these accidents have become the reason why the Tosa Inu aggression is its defining trait.
The trait that typically gets little attention is their laid
With the proper training, these massive dogs become gentle giants that are devoted to keeping their owners happy. They’ll even be gentle with children and become very-well mannered dogs that'll make your life much easier.
In these ideal circumstances, the Tosa Inu is a fantastic pet that would be an excellent addition to your family. But understanding whether or not you fit those ideal circumstances is something to think about before making a final decision.
Another challenging part of the Tosa Inu temperament is its high level of intelligence. This dog is capable of doing a lot of things on its own and will be more independent than you might imagine. Their intelligence makes these dogs quite stubborn and harder to deal with as a dog owner.
But this level of intelligence does have its perks. It makes the Tosa Inu more conducive to training as new concepts come easy for them. You could teach them to do almost anything, and they’ll obey as long as you present a strong, commanding front.
It also gives them an advantage as a watchdog with their ability to detect threats with their cool and calm demeanor. An intruder would have a hard time outfoxing a Tosa Inu and entering your home.
A Brief Tosa Inu History
According to most experts, the Tosa Inu or Japanese Mastiff has been known in Japan dating back a 1,000 years. These dogs originated on the island of Shikoku in a place called Tosa Wan; hence, where he got his name.
Although the Tosa Inu’s well-known for their fighting ability, he didn’t start off this way. In fact, the earliest Tosas were spitz dogs, which is a far cry away from what they’re currently. It wasn’t until 19th century that Tosas started picking up the traits they’re well-known for today.
During this time, Western breeds were introduced into Japan. Naturally, breeders thought it’d be a good idea to crossbred Tosas with breeds like M
As a result, the Tosa Inu quickly became known for their fighting ability. These dogs were thriving until the second world war came along, which almost made the breed extinct. Japan just didn’t have the resources to feed its people, let alone a 150-pound fighting dog.
Luckily, a few were placed on an island called Hokkaido for safe keeping. This island is where they stayed until the war ended and it became legal for people to own them again. After the war, they were reintroduced into society and were even recognized by the United Kennel Club in 1998.
The Ins and Outs of Tosa Inu Training
In an ideal situation, the training for a Tosa Inu puppy should start as soon as possible: even as early as eight weeks would be an appropriate time to begin training sessions.
If you wait too long, you’ll
These sessions should consist of socializing him to the point where he no longer views strangers and other dogs as threats.
Around the 10 to 12-week mark, you should start thinking about enrolling him in a puppy training class. You should also bring friends over to meet him. These situations will force him to understand that not all dogs and strangers are threats.
It’ll engrain these proper behaviors into his a mind at a young age. And when you’re comfortable enough with the training, have him meet your friend’s dog. In these early stages, it’s best to keep these meetings on neutral territory.
For instance, a nearby open field, on a walk, or even at an empty park should do the trick. Having them meet each other at your home or your friend’s home could cause some significant issues.
One of the dogs might feel territorial and end up snapping, which could bring out those fighting instincts.

Relevant Health Issues for the Tosa Inu
The sad truth is that every dog has the potential to develop a genetic health issue. It’s just how nature works. But in this breed’s case, the following conditions are the ones that are most likely going to become an issue:
With these conditions in mind, it’s best you keep detailed track of your dog’s background. You should ask the breeder for evidence that the dog’s parents have OFA or PennHIP clearances for hips. This information should give you some idea of whether or not hip dysplasia will be an issue.
If the breeder doesn’t provide you with this information, you should run away fast. These clearances are standard operating procedures for reputable breeders. If they don’t have them, it’s most likely because something fishy is going on at that facility.
For bloat and GDV, all you have to do is watch the speed of their eating. These two conditions are usually the product of a large dog eating too fast; it’d be a good idea to separate their food intake into two or three sessions throughout the day.
And for the eye conditions, keeping a routine vet visit should ensure your Tosa Inu’s eyes stay in good shape.

The Grooming Requirements of the Tosa Inu
As a short coated dog, the grooming requirements for Tosa Inu aren’t too extensive or complicated. But when grooming is necessary, it’ll end up taking a significant amount of time given their massive size.
A good guideline to follow is bathing them every three months. You should use a mild vet-recommended dog shampoo, which is soothing for his coat. It’s also a good idea for you to invest in a high-quality bristle brush and use it once a week.
You’ll want to use coat conditioner to improve their coat’s sheen as well. Another area of concern is the Tosa Inu’s facial wrinkles, which can be prone to getting skin fold infections; use a damp cloth and dry them to avoid this from happening.
Other than these few things, the rest of the Tosa Inu’s grooming requirements are general care things:
- Checking their ears weekly for buildups
- Trim their nails monthly
- Brush their teeth regularly
