Origin of the Fila Brasileiro

Due to the need for the first settlers in Brazil to have an energetic and strong working dog, the Fila Brasileiro appeared. The earliest historical records of this breed of dogs date back to 1671, but the specific origins of Fila Brasileiro are unknown. Nevertheless, everyone agrees that they emerged through the crossing of 3 different breeds of dogs: old dogs of prey or bulldogs, English mastiffs and bloodhounds. Although it is also believed that the third row also participated in this breed cross and from there was born the current Fila Brasileiro breed.

Among the old Bulldogs like the engelsen doggen, the Fila Brasileiro dogs have inherited their raised ears, fur colors and a higher cross rump, as well as a stubborn and aggressive temperament. In exchange for the old English Mastiffs, these dogs have inherited their size and stoutness, with a broad and solid head, a short neck and a curved rump. And the Fila Brasileiro has inherited the Bloodhounds their magnificent abilities of dogs of tracking, as well as their most remarkable physical characteristics for that, such as the lips and the jowls suspended, the drooping lips or the loose skin.

The first official breed standard was drafted in 1968 and since then some have been used as show dogs. In 1982, Fila Brasileiro became considered the most popular dog breed in Brazil. Currently, this dog can be seen as a show dog but mostly as a pet.

Characteristics of the Fila Brasileiro

The Fila Brasileiro is a large dog, very strong and powerful. With a slim figure and slightly longer than its size, it only shows part of its attacking abilities. He has a high body mass for his height, although he does not show great disproportion. The head is also large and strong, and remains proportional to the rest of the body. It ends with a wide and powerful muzzle, from which we can guess a powerful and hard bite. The eyes are medium in size and almond shaped, they can be dark, but also in different shades up to yellow.

This dog is distinguished by its large hanging V-shaped ears and a wide tail which generally leads halfway up and should never be twisted. One of the most remarkable characteristics of the Fila Brasileiro is the shape that its skin acquires in the baleen, very obvious, and that is that in a large part of its body, the skin is loose and very thick, so it moves from side to side when the dog is moving. In addition, his way of walking is unique and very special in everyone canine, and it is that this dog moves the legs on each side of the body at the same time, so its movement is more similar to the way of walking camels than that of dogs.

The size of the Fila Brasileiro is impressed by its dimensions and its resistance. It is a large breed of dog, which can easily measure between 75 and 80 centimeters at the withers in the case of males, although it is always a little less in the case of females. As for its weight, the minimum is generally 50 kilos, but the maximum can be much higher, since it is a very large dog.

However, white, gray, blue and black and bronze are not supported as a base. White spots on the legs, chest and tip of the tail are accepted.

Character of Fila Brasileiro

The Fila Brasileiro character is the most important and significant part of the breed, on which all its fame is built. Unfortunately, the character is very contradictory. Since they are kept exclusively as guard dogs, specific features are expressed in it.

But, unlike other breeds, the Fila has a high level of aggression towards humans, especially in dogs living in Brazil. It is extremely important to understand that these dogs are not suitable for everyone, moreover, they will not suit most.

Only those who have experience of keeping large, aggressive dogs can get a Fila Brasileiro. With the right upbringing, this is an excellent watchdog and protector, but in inexperienced hands a source of serious problems.

Brazilian Mastiff dogs are renowned for their loyalty, which is even reflected in the saying: loyal as a fila. They form incredibly close relationships with their family, for which they will do everything.

If a puppy grows up in the company of one person, then it will be devoted only to him, if in the bosom of his family, then to everyone.

The peculiarity of the breed is ” hates ” or distrust, extreme suspicion of strangers. This is the only breed in which the standard is prescribed intolerance to the approach or touch of strangers. Socialization and training are absolutely necessary, without them dogs will be extremely aggressive towards any outsider.

With proper training, most dogs will tolerate strangers, but only in the presence of their family. However, without it, they cannot stand anyone, which creates extreme difficulties for postmen, firefighters and even those who have to feed the dog during the absence of the owners.

In addition, they take a very long time to get used to a new family member, and some never accept them.

Incredibly protective, always on the alert, suspicious – ideal guard dogs. Only a stupid thief will ignore the barking and growling that a Fila Brasileiro makes.

He’s a great deterrent in his own right. It is considered by many to be the best guard dog in the world.

Although aggression towards other dogs is usually lower than towards humans, many have it as well. They do not tolerate other dogs, even the calmest fila is dominant by default. Any aggression towards another dog can result in the death of the enemy, since there are not many breeds that could resist it.

It is recommended to keep only one dog. If the puppy grew up in the company of other animals, he considers them members of his pack and protects them. However, this does not apply to the rest, and he can simply tear someone else’s cat.

Like other aggressive breeds, Fila Brasileiro is difficult to train. They are not servile; they live as they see fit. Most are incredibly stubborn, many are wayward.

Under no circumstances they will listen to the command of someone who is considered lower on the social ladder, and this means that the owner must always be higher than his dog.

This does not mean that it is impossible to train them, just training requires experience, knowledge, time and effort. At the same time, even the most obedient periodically show self-will.

Fila Brasileiro is more active than most giant breeds. He cannot be satisfied with a couple of short walks. At least 60 minutes of active loads per day, preferably more.

They love walking, but they feel best in the spacious and safe courtyard of a private house. They patrol the perimeter and are poorly suited for keeping in an apartment.

Potential owners need to be aware of some of the breed’s characteristics. They will bark at almost anything they consider suspicious and will be noisy neighbors. Also, not suitable for very clean people.

In addition, they may mistake children’s games for aggression and react accordingly.

Basic care

A cramped apartment is not the best option for maintaining a Fila Brasileiro. It is also not recommended to keep such an active dog on the chain. If you own a private house with a personal plot, then Fila Brasileiro is perfect as a pet. Arrange for him in the yard a spacious range with a large booth or house, these will be ideal conditions of detention.

Of course, the fila can also live in the apartment. It is important that you walk it twice a day daily. Each walk should last at least an hour. It is recommended to walk in the morning and in the evening. Thus, the dog quickly learns to cope with its natural needs at certain times on the outside.

Some owners, fearing that their fila dog will freeze at night on the outside, take the pet into the house. As a result, all households and the dog feel discomfort.

  • Frequent bathing is not recommended, as water treatments can disrupt the protective layer that the dog’s skin releases. This layer protects the Fila Brasileiro dog, not only from temperature changes, but also from insect bites. So, arrange a planned bathing 2 times a year. The rest of the time, wipe the wool with a rather damp towel and wash the feet after walking.
  • We brush our dog’s teeth twice a week to prevent dental diseases and remove bad breath from the mouth.
  • Ears are the weak spot of a Fila Brasileir. Often these dogs have inflammation, infectious diseases. In most cases, the cause is anatomical features.
