The Fila Brasileiro, also known as the Brazilian Mastiff is linked to aggressive behaviour but has never been used as a fighting dog.

The UK, Denmark, Australia, Malta, and Cyprus have all banned the breed. The Fila dog is not recognized by the KC or AKC although it has been accepted by the CBKC and the FCI.

The people of Brazil have a saying ‘Faithful as a Fila’. It is a tribute to the remarkably loyal personality of the breed.

They are prized in their native land, owning the title of the National Dog of Brazil. This giant breed is exceptionally hard-working but requires a firm, experienced owner.

Fila Brasileiros can be dangerous in the wrong hands.

Extremely territorial, nothing will get past the Fila Brasileiro. The home, land, and livestock will remain safe under their watch.

The powerful and dominant temperament should only be handled by those with experience. For this reason, first-time owners must steer clear!

Fila Brasileiro puppies excessively chew and their large jaws can cause some serious damage. Before bringing home a new puppy, ensure they have a variety of chew toys.

This giant breed also has large jowls and will drool heavily, especially after eating and drinking. Keep a towel nearby to wipe their mouths.

A distinctive characteristic of the breed is its gait which is known to resemble a camel’s walk. Their smooth short coat is found in colors black, fawn, and brindle.

Markings of white are accepted so long as it doesn’t cover more than a quarter of the body.

The Fila Brasileiro originates from Brazil but their exact historical background is vague. They have been in existence for the last 400 years working throughout the Colonial period.

Its genetic background has links to the English Mastiff, Bulldog, and the Bloodhound.

Fila Brasileiros were bred to work on farms and plantations typically found in the tropical rainforest.

They were used to protect livestock from predators such as the Jaguar and would also hunt. Their job was to capture as opposed to killing.

The breed would also chase runaway slaves, pinning them down by the necks until the slave master arrived.

It’s their incredible sense of smell that allows them to effectively track down prey. Many believe this trait and their saggy skin is derived from the Bloodhound.

These canines may be large in size but that doesn’t stop this agile breed from reaching speeds of up to 35mph!

Commonly the Fila Brasileiro was associated with Paulhistas. They were slavers, traders, and explorers from the state of São Paulo.

Extreme working temperatures make the Fila Brasileiro the most heat tolerant of the Mastiff breeds. Fila Brasileiros were popular right up until the 19th century.

Unlike other breeds used to capture slaves, the Fila Brasileiro did not become extinct.

By the 20th century, the need for a Fila Brasileiro had changed. Crime increased dramatically across Brazil, leaving many to source the Fila Brasileiro as a form of protection.

It is thought this period attributed to the aggressiveness of the breed. Despite being banned in certain countries, the population of the Fila Brasileiro dog breed is on the rise in Brazil.

It is incredibly important a Fila Brasileiro puppy is well socialized throughout its early years.

Group puppy classes are a good way to introduce them to other dogs and strangers, whilst learning commands.

The Fila Brasileiro’s short, smooth coat is rather dense and sheds moderately. Shedding is at its heaviest during the Spring and Autumn seasons because of a coat blow-out.

Brush them once a week using a bristle brush or grooming rake to remove dead fur. It also redistributes the coat’s natural oils.

The folds of the Fila Brasileiro’s skin are prone to infection because of moisture and bacteria build-up.
