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.
Chihuahua is a state in the country of Mexico. From this state, the dog breed Chihuahua and the “teacup, or toy” chihuahua take their name. Interestingly the Chihuahua Club of America maintains that “teacup” Chihuahuas do not exist and that the size differential is normal for the breed. Chihuahuas or their ancestors have been around a very long time, sadly the exact origins of the Chihuahua are lost into the pages of history, but archaeological clues such as wheeled dog toys, art, and pottery link the Chihuahua to Mexico and to the Techichi dog. The Techichi dog at the time of the Spanish Conquistadors was sold for food (not unlike we sell beef or chicken) and also as a companion dog to death. Cortez even mentioned the Techichi dog in a letter sent back to Spain, describing them as being raised for food and sold in the marketplace.
When a death occurred a dog was chosen as a companion and cremated with the deceased. It was believed that the dog helped the soul of the decedent reach their eternal destination. The Techichi dog from which the modern-day chihuahua likely descended was very plentiful in the central American area that is now the country of Mexico and raised by the ancient Toltecs and later the Aztec people.
Chihuahuas are little dogs and come in a variety of coats, head shapes and even (within the designation small) sizes. The designation “teacup, toy or pocket” while not an official breed name is a useful descriptor, since they are the littlest of an already small breed and these minute pets, as puppies, may fit into a teacup or a pocket.
Fortunately while no longer a food source, the chihuahua is now sought after as a loyal and lively pet and companion.
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.
Chihuahuas are small. Even the bigger ones are only about six pounds and a “teacup” or “toy” is often three pounds or less. Their bodies are slightly longer than they are tall, but even the tallest are not over nine inches. Chihuahua standing under five inches in height is not uncommon in the “teacup” or smallest of these dogs. They have two different head types and a domed skull. One type of head shape is like a deer while the other is described as an apple-shaped head. The apple-shaped heads are more popular than the deer shaped heads, although sometimes in the “teacup” especially the soft spot fails to close at maturity when growth is complete and the bones should knit, therefore leaving a soft spot in their skull – this is called a molera.
Like different shaped heads chihuahua may have long hair or short-haired coats. The short-haired coats are smooth. The Chihuahua coats may be a large variety of colors ranging from black to white, with red, brown, fawn, cream and chocolate and they may be solid-colored, spotted or sabled. Personal preference is the determining factor on the type of coat a pet Chihuahua has since the breed does not have a preferred color, pattern, hair length or feel. Their muzzle (nose/mouth combination) is short and pointed. Chihuahua have have naturally erect pointed ears and large round eyes. A Chihuahuas tail is relatively long and mostly either curled up and over the back or carried up.
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.
Children friendliness very interactive with family but has been known to nip at small children and bark, so no not really
3. Adaptability yes but they are better off in apartments and homes not out in the country where their size makes them targets for predators.
4. Learning ability average ability to learn but Chihuahua can be but stubborn which may impact ability and willingness to learn.
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.
Chihuahuas live on average fourteen to eighteen years. There are some issues that may cause concern or lower life expectancy.]
• Hypoglycemia (low blood sugar) is something to watch for. Low blood sugar can cause death in just a few hours but when caught is very easily treated. Some of the symptoms are being uncoordinated when walking, acting sleepy or lethargic, unfocused sight, fainting, having a seizure or having spasms in the muscles of the neck. First aid can right this condition with a sweet supplement like corn syrup, or honey. This is more common in puppies, but the teacup chihuahuas are susceptible.
• Hydrocephalus (water on the brain) can affect many toy dog breeds. The puppy or dog will appear to have an oversized head, and be slow (display lethargy) and grow slower than its littermates.
• Pulmonic stenosis (a heart condition) occurs when the right ventricle is impeded. Teacup Chihuahuas are also susceptible to heart murmurs.
• Collapsed trachea this occurs when the cartilaginous rings in a Chihuahua do not form completely or weaken. This can be hereditary or an acquired condition and occurs in other small breeds of dog.
• Molera – where after finishing growth a soft spot remains in the skull and the bones do not knit. As a puppy, the owner must remain vigilant about head injuries.
• Obesity (overweight). Most of the time this is a result of the Teacup Chihuahua being overfed. Obesity can contribute to a shortened lifespan and chronic bronchitis.
• Cold susceptibility. Cold weather can cause Teacup Chihuahuas to shiver or tremble when exposed and during cold temperatures, the dogs may need to wear a sweater and boots outside and cuddle with their owners under blankets or bask in the sun to stay warm.
• Infected or injured eyes. Due to the prominent eyes, exposure to irritants such as dust, allergens, or dry air can cause the dog to develop this beginning with watering eyes.
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.
1. Feeding the Puppies. Puppies should be fed four times a day. Underfeeding can cause the issues of low blood sugar and overfeeding can result in obesity increasing the risk of other health complications.
2. Feeding the Adult. Adult teacups are also vulnerable to hypoglycemia and obesity. Of course, the low blood sugar will be much more acute than obesity and need prompt care if it occurs. Adult teacups should be fed twice a day.
3. Points for Good Health. The chihuahua generally exhibits more vigor and endurance than pet owners expect from such a small breed of dog.
4. Games and Exercise for Teacup Chihuahua. Go ahead and run and play but remember even with the unexpected stamina and endurance this is a very small dog, small legs, using discernment, judgment, and restraint so the games and exercise is fun and builds health and is a special bonding time, without jeopardizing the sugar levels or causing exhaustion or misery.
