The American Staffordshire Terrier is a part of all the confusion surrounding the group of “pit bulls”. The American Staffordshire Terrier is directly related to the English Bull Terrier and English Terrier. The breed of the English Staffordshire Terrier was bred in the early 19th century in the West Midlands. It was not until later that the breed came from Staffordshire. These English Staffordshire Terriers are also the source of contention by breeders who insist it was the Fox Terrier, White English Terrier, Tan and Black Terrier that are the ancestors of the English Staffordshire Terrier.
These terriers (AKA pit bull terrier) came to the United States in the mid 1800’s. By the late 1890’s they were accepted by the United Kennel Club (UKC)as the American Pit Bull Terrier – a new and distinct breed. There were also some that were accepted into the AKC as the Staffordshire Terrier. In England they were still known as the American Staffordshire Terrier. When the AKC accepted the breed in 1936 they were given a new standard, new purpose and new group – the terrier. In 1969 the American Kennel Club recognized these dogs as American Staffordshire Terriers and refused to recognize the American Pit Bull Terrier. The name was changed to move the breed away from its characterization as a bull fighter and to distinguish it from the smaller English Staffordshire Terrier. All American Staffordshire Terriers are directly related to the American Pit Bull Terriers.
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
The American Staffordshire Terrier is a strong, powerful dog – stocky, muscular and graceful. At one point in time the American Staffordshire Terrier and the American Pit Bull Terrier were considered to be the same breed. Even today there are those that make that argument, but they have been recognized outside the AKC as separate breeds. The AKC only recognizes the American Staffordshire Terrier and not the APBT. However – even though there have been decades of separation in breeding the American Staffordshire Terrier and the American Pit Bull Terrier are the very same dogs genetically.
The American Staffordshire Terrier has a broad skull, high set ears and pronounced cheek bones. Their ears should not be cropped by AKC standards and their eyes are far apart, round and dark. With a medium sized muzzle and a heavy muscular back, they are as powerful as they look, if not more so. Most have black noses. The AmStaff has a broad, deep chest with wide set forelegs and compact feet. The tail is short and tapered and it should not be docked.
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.
The American Staffordshire Terrier is a loving, gentle dog that wants nothing more than to be with and please his people. Contrary to his reputation as a “killer”, this dog is actually a lover. They are great with children and want to be a part of the family. They even think they are lap dogs, regardless of their size. They are never going to be aggressive toward people and even though they are not one-person dogs, they are loyal, and they are devoted to the family and the “leader of the pack”.
This breed can tell who is their friend and who is not. They are not aggressive, but they will protect their own. They are courageous, confident, attentive, bold and strong-willed. The AmStaff gets along with other dogs most of the time, but they will never back down from a challenge and should never be left unsupervised with another dog. They should not be loose in a neighborhood or at a dog park. No matter how much you trust your American Staffordshire Terrier they can be killers in any fight with another dog.
In addition to this you must socialize and train your AmStaff. You need to be the pack leader and be in control. The AmStaff wants to please you so for a strong leader they will respond positively to positive training. They are intelligent and pick up quickly on what you want them to do. However, they are incredibly strong physically so training them to heel and walk with you obediently is a must. A well trained and exercised American Staffordshire Terrier is a happy dog and a loyal family dog.
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.
For the most part the American Staffordshire Terrier, like most of the “pit bulls” is a hearty, healthy dog. They have a few tendencies that breeders should test for including hip dysplasia, allergies, and heart issues. They can test for Cerebellar ataxia, which has affected the AmStaff with a progressive decline in their ability to control their muscles and coordination.
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.
feed You can feed your American Staffordshire Terrier either commercially purchased food or food you make yourself if the quality is high, nutrition is good, and the amount eaten is determined by the owner. Do not free feed. The AmStaff has the tendency to become obese. Its ok to use treats for training and rewards, as long as its use is controlled.
As previously mentioned the American AmStaff Terrier has a tendency toward a few health issues. Hip Dysplasia – this condition causes a lot of pain and disability. It leads to different types of arthritis and degenerative joint disease. Cardiac Issues – Congenital heart disease consists of vessel malformation and lesions.
The AmStaff can be susceptible to Autoimmune Thyroiditis. This is a form of hypothyroidism developed by dogs. It is usually seen between 2 and 5 years of age. Continual retesting is recommended.
This is the most dangerous disease possibility that the American Staffordshire Terrier faces. There is a test for this condition which causes the AmStaff to display an inability to control their muscles and a loss of balance, to the point of falling. This is a progressive disease that often leads to euthanasia. The Staffordshire Terrier Club of America suggests that AmStaffs carrying the NCL genes should never be bred.
The American Staffordshire Terrier is an energetic, and athletic dog that loves to play and needs plenty of exercise. This breed is oriented to people and should never be left alone in the yard all day as a way for her to exercise. She needs you to play with her.
