Kurī, also known as Guri or Peroor New Zealand Native Dog, is the Maori name for this dog which was introduced to New Zealand by the Maoris when they migrated from East Polynesia around 1280 AD.
They were in fact Polynesian dogs which died out in New Zealand. The Māoris would use the dog as a food source and the skins would be used to make some form of clothing. The bones were used to make items such as necklaces and fish hooks.
Not surprising then that the dog became extinct in New Zealand, with the last known Kuri specimens being found in the Museum of New Zealand Te Papa Tongarewa.
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 Kuri is extinct now but it was a small to medium sized dog with a thick set neck. He stood between 25 and 46cm and weighed about 13 to 15 kilograms.
He had thick medium-length rough textured hair, small head, erect ears, short legs and a bushy tail. The color of their weatherproof coats varied and some were black, some white or cream and some were a mix of colors and patterns.
An interesting feature about them is that they didn’t bark but instead they howled. They were good at hunting birds.
The Kuri wasn’t considered the brightest breed, but he would have benefited from some training and socialization as this just makes a dog a better pet in every sense – more obedient and better behaved in all situations.
Some Kuris were friendly and able to bond with their human owners, while others were independent and somewhat aloof. Their size would have allowed them to be kept in the city or the country as they weren’t particularly energetic dogs, not requiring much ground to run around in.
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.
It appears as though some Kuris were kept as pets and that they were able to develop loving relationships with their owners.
We don’t know too much about the extinct Kuri, but scientists are now studying and analyzing the hairs of the dog to find out more about it, and specifically why the Maori dog disappeared some time in the 19th century without a trace.
They will also be analyzing Kuri bones salvaged by archaeologists and which were found on rubbish heaps. These bones can be tested to see whether the diet of the Kuri changed much between the days of Maori settlements and the arrival of the European settlers.
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.
He also doesn't come as recommended for small, cramped homes in the city. He’s just too big and he will need to get out and be walked often.
You want to create a home for him that ensures he is the calm, gentle dog he is capable of being, If you’re fair, firm, caring, patient and consistent, then this big dog might be for you. With the right care he becomes a gentle, devoted pet.
Some Kuri dogs scavenged while others were pets and ate well. The lifestyle they led would have determined their health. In those days they would have suffered with dental disease, common in adult dogs. Left untreated, dental disease can lead to dental tartar buildup with gum inflammation and tooth loss.
Dental disease can also lead to other organ diseases. These days brushing your dog’s teeth with canine toothpaste and toothbrush can help to ward off dental disease.
Those Kuris that weren’t pets, tried to survive scavenging, and their homeless situation could well have led to ear infections – caused from a wax- and dirt buildup within the ear. He would have been frantic trying to scratch his ears. In modern times, if your dog showed signs of an ear infection, you would need to get him to the vet.
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.
The Kuri will have required regular grooming which means a brushing down twice a week. Brushing would have been useful to prevent loose hairs from shedding with the dog. He would have had to have his ears and eyes checked too to avoid infections. Brushing him would have given his owner the chance to check him over for fleas and ticks too.
As the Kuri wasn’t an overly energetic dog, a walk a day would have kept him content and fit.
The Kuri was a dog that essentially formed part of someone else’s diet. Those that managed to escape being a meal for someone no doubt had to scavenge for food. Because they were used to help people catch birds, they themselves were used to catching birds for themselves.
As a small to medium sized dog, if you were to keep such a dog as a pet you would have given him a cup or two of dried kibble a day and tried to vary his diet by including some home-cooked food and raw meat.
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.
