The Shih Tzu is an Imperial Chinese breed developed by palace breeders hundreds of years ago with breed stock from the Tibetan lines. It is quite probable that the Shih Tzu was originally a cross between two Sino-Tibetan ancient dogs – the Pekingese and the Lhasa Apso. Based on their looks, the Shih Tzu means the lion dog, but they were really very pampered palace dogs living with the Chinese emperors and families. The emperors were always gifting the breeders who developed the most affectionate, gentle and beautiful Shih Tzus.
Until the 1930’s the Shih Tzu was not known to the world outside the emperor’s palace. Once the breed did come out from behind the palace walls, they were immediately popular. Much debate went on about how to refine the breed as clubs began to spring up in Peking and then in England. It was not until 1969 the Shih Tzu was recognized and entered in the AKC Stud Book.
While the original Shih Tzu might have been a mix between the Pekingese and the Lhasa Apso, today’s breed spread around the world after the second world war. In Europe in the 1930’s the breed was classified as Apsos. In 1935 the first Shih Tzu Club of Europe was formed, and the first standard was written, and the breed was categorized as the Shih Tzu.
Following World War II, soldiers brought the dogs to the States from Europe. By the 1950’s the breed was growing in popularity and the AKC recognized the breed in 1969 as members of the Toy Group. They are now recognized by all major kennel clubs throughout the western world. They are recognized by the Federation Cynoloqique Internationale in the Companion and Toy Group, among Tibetan breeds.
The Shih Tzu is a good watchdog, but it was bred to be a companion animal. It is a friendly, open breed that welcomes strangers. They are great with other animals and children as well as adults.
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.
This is a breed of lively, sturdy and alert little dogs with a beautiful double coat that is flowing and long. In its full glory the Shih Tzu coat is touching the floor all the way around the dog. The dog’s bearing is as royal as its history, arrogantly carrying his head high and his tail curving over his back.
The Shih Tzu is a solid, compact breed with weight and substance. They may be a small dog, but they are a strong one. They have large dark eyes with a short muzzle and fur covered drop ears. They are just a little longer than they are tall with a distinct underbite.
There are a few differences between the European or UK Kennel Club standard and the American Kennel Club AKC standard. As opposed to the UK standard the AKC standard states that:
• The hindquarters are muscular while the front are straight. They are balanced in that they are not too long or too short.
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.

For many breeds that have the advantage of isolation like the Shih Tzu did with the emperors of China usually have very little genetic health issues. Most of the breed is indeed healthy but there are some issues.
• Brachycephalic airway obstructive syndrome due to the shape of their face and head causes them to have breathing issues. They cannot handle heat and they cannot swim. They can have an upper airway obstruction that makes it hard for them to breath. If this is bad enough, surgery may be required.
• Hypothyroidism – thyroid does not produce the hormones necessary for metabolism to work effectively. This can lead to weight gain, hair loss, lethargy and muscle loss. It can be treated effectively.
• Issues of the eyes include – cataracts, corneal dryness and inflammation, progressive retinal atrophy, improperly closing eyelids and retinal detachment.
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.
1.Feeding the puppy – this is a toy dog so don’t overfeed. They have a tendency to become obese. Calorie and weight level need to be calculated with any diet you feed. The diet should be high quality with plenty of protein made for toy dogs. Feed the puppy at least 3 times a day, maybe four in very small amounts, never more than ½ cup per day.
2.Feeding the adult - this is a toy dog so don’t overfeed. They have a tendency to become obese. Calorie and weight level need to be calculated with any diet you feed. The diet should be high quality with plenty of protein made for toy dogs. Feed the adult once or twice a day in larger amounts than the puppy but never more than ¾ of a cup per day.
3.Points for Good Health - most Shih Tzu’s are hardy with exceptionally good health.
This is a pampered, not high energy dog. However, she still needs playtime, which can be indoors and short walks outdoors every day.
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.
