Fila Brasileiro vs American Hairless Terrier - Breed Comparison

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.

Derived from the Rat Terrier, the American Hairless Terrier was born in a litter of Rat Terriers in 1972.

The evolution of this breed is very different from other hairless breeds. The American Hairless Terrier was independently developed when a hairless pup was produced in a litter of normal Rat Terriers. The owners of this pup, Edwin and Willie Scott attempted to breed her to other Rat terriers but were not successful in having another hairless pup until years later. Then they had a litter with one male and one female hairless puppy.

From that point on they worked with a veterinarian and a geneticist to develop the breed until it was accepted as a separate breed from the Rat Terrier in 2004 and accepted into the AKC in 2016.

The breed is very rare and with hairless dogs breeding only produces about two thirds of the litter as hairless and one third as coated. If a hairless is bred to a coated terrier, the chances of getting hairless puppies are 50% hairless and 50% coated. It is very rare to get a hairless when breed two coated terriers. The difference between the American Hairless Terrier and other hairless breeds is that the hairless gene in most breed is a lethal dominant gene, but in the AHT it is a recessive gene.

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.

Temperament:

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 Hairless Terrier is similar to it’s breed of origin, the Rat Terrier, and the coated AHT looks very much like a Rat Terrier. They are small to medium in size, very muscular and have more refined features than the Rat Terrier. Their round eyes can be a variety of colors including amber, brown, grey, turquoise and blue. The tail is not docked but rather long and thin.

The AHT might have eyebrows and whiskers or they might only have whiskers. Their head is broad, and wedge shaped with upright ears. They are an energetic, social and intelligent dog.

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.

This is a curious, intelligent, little dog. They are terrific family dogs with a note to say they are better with older children than with younger. If they are raised with small children, then they are terrific with them. They are territorial, and the children become part of their territory. They will guard and protect them.

They need to play, and this is the biggest requirement for owners. Be sure you have time for them. This is not a couch potato dog. They have a lot of energy and can be destructive and “barky” if that energy is not dissipated. They are terriers through and through and love to “go to ground” whether going in holes they find or digging the holes themselves. They will go after small rodents like chipmunks. They need to be protected in these activities since their skin is vulnerable to scratches and cuts from brush. Their prey drive is strong, so it is important to protect them from themselves in this respect.

They are curious and feisty and every inch the terrier. Affectionate, friendly, and social it is also important to remember they can be scared easily, hurt if play is too rough, and this will trigger barking. They make very good watch dogs.

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.

There are not many health problems bothering this sturdy little dog.

The American Hairless Terrier has limited breeding stock and it is still a rare breed. Its health problems are mostly related to its hairless state. The breed is highly susceptible to sunburn, rashes, pimples, and allergies. They often need clothing in all seasons to protect them from the heat of the sun or from the cold. The skin must be cleaned regularly often daily with soap and water. This is especially true if sunscreen is used as they are open to skin infections.

Hip dysplasia is also a common issue for this small breed.

Exercise and Space:

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 .

Grooming:

Moderate shedding. Regular brushing twice a week will be required. Check ears for infection and brush his teeth 2 or 3 times a week.

Diet:

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.

The American Hairless Terrier has some food needs that might be different from other breeds. They should not be given food that contains soy, wheat or corn. They need to be fed at least 3-4 times a day in small amounts as puppies and twice a day as adult. Be sure to avoid overeating and obesity. Puppies need about 400 calories a day whether you feed four times or two times. The adult American Hairless Terrier needs about 500-600 calories per day. This might be half a cup to a cup per day.

Health issues

As previously mentioned the American Hairless Terrier has skin health issues and is also prone to hip dysplasia.

Exercise and games

This is a great breed for games if you make them small to match his size. He is energetic, athletic and playful. He loves agility, lure chasing and barn hunt activities. They need a good half hour of vigorous exercise per day.
