Tea Cup Chihuahua vs Cao Fila de Sao Miguel - Breed Comparison

This Molosser type dog originated on Sao Miguel Island in the Azores, a region of Portugal. Known also as the Sao Miguel Cattle Dog or the Azores Cattle Dog, the existence of the Cao Fila de Sao Miguel has been documented since early in the 19th century.

The dog has always been used as a cattle dog but today it remains rare outside of Portugal. In was in 1984 in Portugal that the first written breed standard was published in Portugal. The Cao Fila de Sao Miguel then earned recognition with the Portuguese Kennel Club.

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 Cao Fila de Sao Miguel is a medium to large sized dog standing 50 – 61cm in height and weighing 25 – 41kg. As with all molossers, the dog has powerful jaws.

The coat of the Cao Fila de Sao Miguel is short and smooth while the hair on the tail and thighs is a bit longer. The Cao Fila de Sao Miguel is always brindled, and comes in shades of fawn, brown, gray or black. A white mark on the forehead around the chest or on the paws is also often seen.

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 Cao Fila de Sao Miguel is a dog who enjoys exceptional health. When you do research you see there aren’t really any particular illnesses plaguing this dog, and he can actually live to be 15 years of age. Be aware of some illnesses as they are common among different dog breeds – hip- and elbow dysplasia, bloat, eye diseases such as progressive retinal atrophy and cataracts, heat intolerance and arthritis.

Dog bloat:

This is a dangerous illness that can affect any dog – small or large. This is when the dog’s stomach fills with fluid or gas so that it expands. The stomach then puts pressure on other organs and your dog can have trouble breathing. There is also no blood flow to the heart. Sometimes the stomach of the dog twists and your pet can go into a state of shock. Recognize the symptoms of bloat – a swollen stomach, drooling and wanting to vomit but nothing coming up. Get your dog to the vet immediately.

Abscess:

An abscess can be so painful for your pet often when your dog has a thick coat it could go undetected. If an abscess on your pet doesn’t burst, or even if another abscess appears, a vet must be consulted and a course of antibiotics given.

Ear Infections:

Ear mites, dirt and a build up of wax may cause your dog to scratch at the ear, shake his head or hold it on one side. There may even be a foul-smelling discharge. Your dog will need to have his ears cleaned. Special ear drops can rectify the problem. Remember that hot, red ears will require veterinary attention.

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.

The Cao Fila de Sao Miguel is a low maintenance breed and all that will be required for him is that you give him a thorough brushing a couple of times a week.

Diet:

The Cao Fila De Sao Miguel puppy will require four meals of puppy food a day. The adult Cao fila de sao miguel can go down to 1 or 2 meals a day after his 1st birthday.

These days you get some excellent commercially manufactured dog foods and your veterinarian can help you choose one suited to this particular dog breed. Add in some home-made vegetables, rice and meat every now and then. The idea is to make sure your dog is getting in all the minerals and vitamins he needs.

There is evidence showing that dogs who enjoy raw meat every now and then enjoy a number of health benefits. Skin and teeth are improved, your dog has a shinier coat, less allergies,less inflammation and he is more relaxed and amicable. Ensure a constant supply of fresh, cool water in a clean bowl and at all times.

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.
