The Old English Mastiff as well as the Bulldog are the breeds behind the Bull Mastiff. The Bullmastiff was originally developed in England around the 1860’s. Gamekeepers in England wanted a large, brave, robust dog which could help with keeping poachers away from their large estates which kept game.
As these large estates dwindled, so did the need for the services of the Bullmastiff and later they were simply bred to be family companions. As more Old English Mastiffs were bred, the dog became lighter, so that light tan or fawn became the preferred color.
The breed was officially recognized by the English Kennel Club in 1924, and the American Kennel Club in 1933.
The Formosan Mountain Dog is most often known as the Taiwan dog and it is a landrace indigenous to Taiwan. It is a small to medium breed of dog that was semi-wild at one time. The colonialization of Taiwan and other foreigners help to fully domesticate the Formosan Mountain Dog. They were found to be very trainable and uniquely suited for the terrain around Taiwan. The dogs were easy to train and now serve as hunting dogs, stunt dogs, guard dogs, rescue dogs, therapy dog and personal companions. There are three types of Formosans two smaller types and one medium. However, the original pure Formosan Mountain Dog is getting close to extinction again because the government and people have provided no protection or conservation efforts for them. These dogs have been living in Taiwan in the mountains and were called Formosan Mountain Dogs when Taiwan was known as Formosa. They come from a line of Southeast Asian hunting/gun dogs and they are considered ‘rare’ now.
According to historian Dr. Sung Yung-yi, the breed went through 4 major catastrophes that affected their development. The first of these was the Dutch Establishment in 1624. The Dutch colonized Taiwan and imported both people and dogs. The dog they brought in was called the Flying Dog and was either Greyhound or Pointer. Eventually, the Flying Dog bred with the Formosan Mountain Dog. This along with the slaughter of dogs belonging to the indigenous people by the government, starting the decline of the original Taiwan dog.
In 1895, it was the Japanese acquiring Taiwan following the First Sino-Japanese War. The Japanese bred the Formosan Mountain Dog extensively with the own Japanese dogs. This further diluted the line and authenticity of Taiwan dogs.
This was followed by World War II when German Shepherds traveled with the US Army and they cross-bred with the Formosan. This was the third major dilution of the Formosan Mountain dog line. At the same time, the Japanese government considered the Formosan Mountain Dog a sanitation threat and barbaric. They massacred them in large numbers in the name of sanitation.
The fourth and final dilution took place during the Kuomintang Era beginning in 1945 with the arrival of the Chinese Nationalist Party. They brought with them the culture of eating dogs. During this time the economy of Taiwan took off and business people began to import their own foreign dogs that were high priced purebreds. These dogs bred with the Formosan and other Formosans were just abandoned to die. The ranks of the breed became very thin indeed. Today’s pure Formosan is highly valuable and extremely rare. Because of all the crossbreeding over the centuries, today’s purebred Formosan Mountain Dog is very different from the Taiwan dog of old. Today’s Formosan is loved all over the island and is a companion and watchdog.
Today there is an effort by Taiwanese ecologists to put together a research project that would study and preserve the Formosan in its indigenous form. Dr. Yung-yi led this effort. He located only 46 dogs with a pure pedigree, 21 females and 25 males. They let the Food and Agricultural of the United Nations know and the dogs were labeled close to extinction. Reproducing from the indigenous dogs to purify and increase the breed was the goal. The government was not very supportive.
Today the Royal Air Force is looking at the Formosan Dog to use for military security. They are currently only using German Shepherds and needed another choice. It was decided that the Formosan Mountain Dog had a better sense of smell, dexterity, alertness, and hearing as well as better padding on their paws.
Through these efforts and those of foundation stock breeders and owners, the Formosan Mountain Dog in its indigenous form was brought back. Some call this dog a purebred Formosan while others consider it a new type. Standards were presented to the FCI for registrations as a purebred. This debate continues today
Bullmastiffs are large, brachycephalic dogs, and heights are between 61 and 68cm and the dog weight anything between 41 – 59kg. While it isn’t particularly tall, the dog is thickly set with a deep chest and strong, muscular legs. The Bull Mastiff has a powerful build and plenty of strength with an imposing look on his face. He is a powerful, active breed with a short coat which is also weather resistant and can be any shade of fawn, red or brindle.
The dog has a black muzzle and the skull is large and square. The ears are set high and are short and floppy. The tail was once docked, giving the dog an even more distinctive, powerful appearance, but these days, due to regulations, the tail is left long.
The Bullmastiff is a loyal, devoted, fearless, protective dog. When he belongs to a human family, he becomes a companion but a fierce protector too, being a territorial dog. They love being with their family and can be good with children too, and even other pets, but proper training and socialization will be important. They aren’t aggressive around strangers, though he does make a wonderful guard dog.
He is intelligent and stubborn and if you don’t want him becoming destructive, even though he is a low-energy dog, you will need to exercise him and walk him every day.
The Formosan Mountain Dog that was seen during Dr. Sung Yung-yi’s research is a medium-sized dog, athletic and fit. It has a deep chest and a slim waist. The ears are half-covered, the nose is black and there is a coating of black on the tongue. This black tongue is the most distinguishing attribute of the Formosan Mountain Dog. The breed has a strong jaw, the skull that is just slightly longer than the muzzle, which is flat and tapered, triangle face and almond eyes. They have a thick coat and upright, curved tail.
The dogs are known to be extremely agile with an ability to hop that is rare in dogs but helps when hunting animals like rats. The Formosan Mountain Dogs hunted in packs with each dog attacking the prey with one bite until it was too exhausted to fight them off any longer.
Contrary to his formidable looks, the Bullmastiff is a gentle, affectionate pet when he has been properly socialized. He is a great pet for families and will guard them with his life. He is loyal and devoted but can be somewhat aloof, particularly with strangers.
He isn’t a highly energetic dog and he is more or less low maintenance and easy-going. Feed him correctly, give him a nice, warm sleeping spot to call his own and give him attention like he deserves as a family member. The Bullmastiff will reward you by being a solid and devoted companion.
The Formosan Mountain Dog is very child-friendly. He is affectionate and loyal to his family and protective of his children.
He is intelligent and has exceptional hunting skills. He is a good guard dog due to his alertness, but they can be fear-aggressive.
He is very adaptable to living in any location as long as there is somewhere for him to get adequate exercise. He is friendly to people and animals.
He is intelligent and learns quickly.
The Bullmastiff is a generally healthy breed, but even so, the breed is known for having to contend with certain health issues. He doesn’t have a particularly long life span either and can live to be about 10, ll or 12 years of age. Some of the more common illnesses to look out for include -
This is a condition where the thighbone doesn’t fit properly into the hip joint. The troublesome part is that it can lead to arthritis, pain and lameness for your pet.
This is a worrisome, life-threatening condition for a dog, particularly for large, deep-chested dogs such as your Bullmastiff. Instead of feeding your Mastiff one large meal, it is recommended to feed him 2 smaller meals. Bloat occurs when the stomach is distended with gas or air and twists, restricting the normal return of blood to the heart.
Because there have not been any studies done on the health of the Formosan Mountain Dog, there is not a lot known about any inherent or genetic health issues. It would seem that some bloodlines are healthy, and others have some serious issues. Especially because there are no studies, it is important for breeders to test for eye issues and skeletal issues through the Orthopedic Foundation for Animals and the Canine Eye Registration Foundation.
The Bullmastiff has a short dense coat which is looked upon as low-maintenance. He will require a brushing twice a week, being a light to average shedder. He is a dog that tends to drool quite a bit so you may need to wipe away slobber from time to time. Because his face has wrinkles, check the creases to ensure they remain free of dirt and food particles to ward off infection.
Check his ears at the same time, brush his teeth at least twice a week with special dog-toothpaste and brush and keep the nails trimmed.
Your large Bullmastiff will require high-quality commercial dog food but he will also need some home-made food in between such as rice, vegetables and meat. He is a large dog and will have to get an intake of raw meat too. Dogs denied raw meat can end up with skin problems as well as other health issues.It is better to feel your Bullmastiff smaller meals than to give him one large meal which he scoffs down quickly. Smaller meals will help prevent the most dangerous illness known as Bloat.
Ensure he has a steady supply of fresh, cool water.
Feed a high-quality puppy food for medium size dogs at the rate of a ¼ cup twice a day until 8 months then ½ to ¾ twice a day until 12-16 months.
1 to 2 cups of high-quality dry food split into 2 meals per day.
Generally healthy breed. Keep clean and watch for mites.
This is an energetic breed and he needs a lot of exercise. He must have at least an hour of exercise daily but the more, the better. He loves swimming and jogging with his people. He’s athletic, smart and agile. He does well with field trials, tracking, agility, and obedience.
