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.
Hailing from Brazil, and known also as the Brazilian Mastiff, nobody seems to be too sure of the exact origins of the large Fila Brasileiro but it is believed to be a cross between the English Mastiff, the Bulldog and the Bloodhound.
Other theories are that the dog comes from a mix of Portuguese and Spanish dogs and that they were bred to guard livestock from predators. Breeds that have no doubt contributed to the modern Fila are the Bullenbeisser, the Bloodhound, Mastiff and Rafeiro do Alentejo. All these dogs have characteristics such as excellent working dog skills, herding instincts as well as courage and tenacity.
The official Brazilian breed standard of the Fila was developed in the 1960s and the Fila Brasileiro Club of America was formed in 1984.
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.
With his huge head covered in loose skin much like that of a Blooohound, and a body resembling that of a Mastiff, the large heavily built Fila Brasileiro is a mastiff breed from Brazil. He stands at 60 to 75cm in height and he weighs roughly 55 to 80kg.
The ears of the Fila are large and droop down or are folded back, depending on his mood. The tail is long and slim. The coat of the dog is short and dense with the texture being quite smooth and soft. Colours of the coat can vary from solid fawn or black to red to brindle.
Perhaps the huge Fila wouldn’t be a good choice as a pet for the first-time inexperienced dog owner as he is a powerful, intelligent, self-assured, headstrong animal that will certainly need to have training and socialization if you want him as an obedient pet in your home.
He is a dog known for his courage and bravery. The Fila is loving and affectionate with his human family, being protective of them and not being too friendly with strangers. He isn't a particularly good pet choice with children in the home.
Some people, after buying a cute Fila puppy, put him out in the yard when he becomes large, and then they pretty much neglect him. This is cruel and irresponsible as he is a social, playful dog who wants to be part of his human family.
These dogs have some aggression in them and this makes them good watchdogs. They generally don’t show aggression towards their family but may snap at a stranger who tries to touch as he feels threatened.
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.
The Fila Brasileiro or Brazilian Mastiff is a powerful dog and it is believed that a large dog like this can be a danger to people if he isn’t trained and socialized.
He is therefore not recommended for first time dog owners or homes with small children. He is a dog that is particularly wary of strangers too.
When he has been properly socialized he can be loving, loyal and obedient because it is essentially how a dog is brought up as to how he turns out.
If you bring one of these big, beautiful dogs into your home, have him socialized as a puppy, treat him firmly, but kindly and you could have yourself an extraordinary pet.
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.
Filas are a dog breed who have a high rate of hip- and elbow dysplasia. This is a serious disease which can lead to lameness with your pet. Other orthopedic diseases with the breed include osteochondritis and luxating patella.
Also, as a deep-chested dog breed, your Fila also is at risk of getting the very serious gastrointestinal syndrome known as bloat. This is a common condition that can prove deadly for your pet. The Fila’s stomach will fill with gas, putting pressure on other organs and stopping blood flow to the heart and difficulty with breathing. Sometimes the stomach will twist. Get him to the vet immediately if you notice a swollen stomach, drooling or restless behaviour.
The Filas size makes it important that he have a good amount of exercise if you want to maintain his health and happiness. He isn’t a dog suited to city life as he is too large and will irritate his owners when cooped up in a tiny space with them. He isn’t demanding when it comes to exercise and activities all the time, but he should still be exercised regularly as he is inclined to become lazy .
Moderate shedding. Regular brushing twice a week will be required. Check ears for infection and brush his teeth 2 or 3 times a week.
Nothing is set in stone as to what to feed your Fila Brasileiro, but a large dog will require quality food with a good amount of protein and fat according to size, age and activity levels.
Because a large breed dog is prone to hip dysplasia, look out for ingredients such as chondroitin and gludosamine which are specifically good for joint health. Try and avoid commercially manufactured food with common allergens such as soy, corn and wheat, artifical flavors and fillers.
A source of cooked rice, chicken and vegetables as well as some raw meat will be excellent for your big pet. Make sure he is never deprived of fresh, cool drinking water.
