Tosa vs Kyi-Leo - Breed Comparison | Petzlover

The Kyi-Leo first came about in the 1950s in San Francisco, USA, with the crossing of two dog breeds – the Lhasa Apso and the Maltese.

Because this is a mixed-breed dog, it isn’t recognized by the American Kennel Club, but it is recognized by some of the other dog associations such as the American Rare Breed Association or ARBA as it is known. Today the dog is looked upon as a designer breed.

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.

Thought to be a dangerous dog breed, it is restricted in some countries.

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 Kyi-Leo is a small dog standing at 20 – 30cm in height and weighing in the region of 4 – 6kg.

He has a long, silky coat which is essentially black and white or grey/silver and white or even gold and white. He has frail legs which can become injured or broken in vigorous rough and tumble games.

Temperament:

You can certainly describe the Kyi-Leo as a sweet, quiet, non-aggessive playful dog, and for anyone who wants a splendid pet and companion, this dog makes a great family pet and he won’t cost you an arm and a leg to feed either.

He also has an acute sense of hearing and this turns him into an excellent ‘alarm’ watch-dog. It is also a dog, that while he will love to join you on a walk, he isn’t a dog that is going to demand a lot of exercise.

He responds well to his human family, is easy-going and gentle, tending to be cautious around strangers. You can trust him to be an awesome playmate for children. In this instance, it’s the children who should be warned when playing with a dog like this as, because of his fragile build, he could easily be injured by children who haven’t been taught to respect animals.

Even though he is such an amicable pet, it will still be of benefit to you and him to have him trained and socialized. Then he responds well to basic commands such as sit, stay and lie-down.

Dogs who spend time with their family, pick up on the ‘culture’ of the family and they learn how to behave. Dogs who are left on their own and never socialized can become nervous and aggressive towards people as they never got to learn how to behave – they weren’t socialized.

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.

Temperament:

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.

The Kyi-Leo is everything you want in a family companion – active, playful, loving, gentle, happy and balanced.

He loves his human family but tends to be a little bit wary around strangers, gradually warming to them.

He may be small, but he is robust and alert, and he is also capable of making you a good watchdog.

The Kyi-Leo is an all-round great little pet to have.

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.

Your Kyi-Leo is such a feisty, robust little dog who is not likely to cost you much in terms of health care. With his frail legs, it is a good thing to know that you need to be careful with him in terms of back-and joint problems.

There are actually knee joint issues which are fairly common in small dogs, one of which is patellar luxation.

Patellar Luxation:

This is where the kneecap pops out of the thighbone, causing the dog to skip or hop. Some joint issues are genetic and may require surgery. Make sure to keep your pet’s weight under control to remove additional stress on the joints.

Pancreatitis:

This is another dog illness you want to be careful with. Acute pancreatitis -inflammation - is when the condition comes on suddenly while chronic pancreatitis is when pancreatitis occurs over a period of time.

With acute pancreatitis in dogs you’ll see symptoms such as vomiting, abdominal pain, tremors and reluctance to eat. Pancreatitis can be brought on by too much fat, especially rancid fat, some anti-biotics, a low protein diet or a sickness such as diabetes.

If you suspect pancreatitis in your dog, get him as quickly as possible 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.

Exercise and Interaction:

The Kyi-Leo doesn’t require vigorous exercising. One walk a day will keep them happy. There are pet owners who believe dogs can be permanently outside dogs where they can do their own exercise.

Everybody who knows dogs, knows they are social creatures who will simply lie at your backdoor just waiting for some response from their beloved human family. Every dog, regardless of breed or size, needs exercise and interaction with their humans every day.

Dogs left alone in the yard day after day are loney, frustrated and bored, and when they start digging or barking, irresponsible owners will ill treat them. These kind of people should never own a dog.

Diet:

The Kyi-Leo has a sensitive stomach so he’ll need good quality food to avoid digestive problems. Ideally home-cooked food such as softly boiled chicken, brown rice and raw or cooked vegetables added into top quality kibble is the preferred diet.

Fresh, cool water needs to be constantly available.

Grooming:

Brush the long, silky coat at least twice a week to ensure it remains free of knotting. Brushing keeps the coat shiny too.

As a long eared dog, ears should be checked and cleaned regularly too. Air doesn’t reach the inside of their ears and the warm dampness in the ears are a breeding place for infection.

Nails should also be trimmed when they become long because left uncut they can hook onto things causing injury ad pain.

Small dogs are more prone to tartar formation and loss of teeth. You’ll notice that something isn’t right because your lively little dog will be lethargic, he may not want to eat his food and his face may be swollen. When you suspect dental problems, get him to the vet.

Diet:

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.

Cool, fresh water should be available at all times.

Grooming:

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.

Exercise:

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.
