Thanks to John D. Johnson from Summerville, Georgia the breed is still with us today. He gathered the best dogs he could find throughout the rural South and bred them back into popularity among his family and other rural families. His father bred the American Bulldog before John did and they have bred them longer than any other in any part of the world. His dogs were regularly used for tracking, hunting, guarding, watchdog and weight pulling. At some point Alan Scott joined Johnson breeding other bulldogs to Johnson's and forming the Standard American Bulldog.
The American Bulldog/ is popular today as a family pet and companion as well as a working dog.
The Tibetan Mastiff is still considered to be a primitive breed originating in Tibet centuries ago. The breed was developed to guard property and livestock. They still do this as well as being a much loved family dog and a show dog as well. There is very little history that is documented for the breed prior to the 19th century.
Believed to be centuries old with ancestors who are mastiff like dogs that developed into two different types of Tibetan Mastiffs. These types are the Tsang-Khyi and the Do-Khyi. The Tsang Khyi were guardians for Tibetan monks, while the Tsang-Khyi guarded flocks for nomadic shepherds and in villages.
The first Tibetan Mastiff was imported in 1847 to England and presented as a gift to Wueen Victoria, from India’s Viceroy. By 1873 there was an English Kennel Club and the breed was labeled a large dog from Tibet and entered into the EKC Stud Book.
The next year the future King Edward VII, brought another two Tibetan Mastiffs to the United Kingdom to show in 1875. The first breed club began in 1931. The world wars interfered and no new dogs were imported to England until 1976. Two dogs were given to the President of the United States in the late 1950’sbut were not bred and it wasn’t until 1970 that any more were imported. The US Tibetan Mastiff Club was not founded until 1974 and they were first entered in a National Specialty show in 1979.
In 2007 the AKC recognized the breed as a working dog since 2007. It’s hard to find a purebred Tibetan Mastiff in Tibet anymore.
The American Bulldog is a powerful and muscular dog in a sturdy and compact frame. The female is more refined than the heavy boned and stocky male, but both genders are athletic, agile and quick. The have large heads, strong jaws, a muscular neck and with a moderately deep and wide chest.
They have a square head, with muscular cheeks and a clearly defined furrow between his eyes. With broad, square and strong muzzles, they have a reverse scissors, scissors, moderate underbite and an even bite. Ears come in a variety of shapes and sizes and eyes can be any color as well. The nose however should be black and lips black as well. Their legs are strong, heavy boned and straight with well-defined muscles in the hindquarters. Finally ,they have a thick, low set tail that comes to a point at the end.
Both types of Mastiffs can be present in the same litter, so that both larger and smaller pups are present. Both types are well-muscled and structured. Today’s dogs being developed in China and the West are much larger than the previous ones. These dogs would be less useful to the nomads and cost too much to feed. Today’s dog is very large with a large head and a long double coat. This coat can be black, brown, gold, and blue, with or without tan markings. There are now a few white Tibetan Mastiffs being bread.
The breed standard for the Mastiff is different in the West than in the East. In the East the breed is broken into two categories – the Lion Head and the Tiger head.
The American Bulldog is characteristically loyal, brave and reliable. It is a friendly, gentle dog that truly loves children. There is not a hostile bone in his body despite his history and reputation for bull baiting. Though he is protective of its family and affectionate with most, he still needs a human companion who is strong willed and a genuine pack leader. Without this he might become aggressive around other dogs and pets. They are immensely self-confident and they do slobber and drool and will become excited and hard to handle without daily exercise of both their body and their minds.
Though generally healthy, the American Bulldog is prone to a few problems.
This is a serious issue in many breeds of dogs and is especially prevalent with the American Bull Dog. This may seem ironic in such a short legged dog but it is unfortunately very common. It is a genetic disorder that causes the bones in the joint to separate and causes the dog much pain and lameness.
Due to skin folds you need to be care and watch for irritation and infection in the folds. They are also prone to ear infections.
The American Bulldog is prone to overeating and all the health issues that presents. With short legs and a genetic predisposition to arthritis and hip dysplasia, obesity is a real health risk for your bulldog.
Though considered a primitive dog and isolated for several centuries, so they should not have as many genetic or inherited conditions as other dogs with more cross and in-breeding. These are the potential health issues they might develop:
Elbow and Hip dysplasia – can lead to lameness and arthritis.
OCD Osteochondrois Dissecans – this is also an orthopedic condition when the soft tissue growth is abnormal in the joints. It is painful and the joint is stiff. Don’t breed a dog that has this condition.
Panosteitis – Canine growing pains. Inflammation of the long bones in large dogs as they grow. They will eventually out grow it. Pain can be managed through medication.
Autoimmune Hypothyroidism – Hormone deficiency leading to flaky skin, weight gain and lack of energy. Can be managed through medication.
Canine Inherited Demyelinative Neuropathy – If your Tibetan Mastiff is going to have this condition, they will have it by six weeks of age. Weakness in the hind legs leading to paralysis.
Bloat – deadly if not treated immediately and related to dietary habits.
Don’t feed the puppy too much protein as you want to prevent Panosteitis and growing too quickly. Do not overfeed. Feed 4-5 cups of high quality large breed puppy food in 3-4 meals day.
4 to 6 or more cups of a high-quality dog food daily, divided into two meals. To avoid bloat do not feed before or after vigorous exercise.
Calm and laid back when inside.
They need 20-30 minutes of vigorous exercise and play daily. They prefer to play with other large dogs.
