Hundreds of years ago the ancestors of the Brazilian Mastiff (Fila Brasileiro) were bred with English Mastiffs, Bulldogs and Bloodhounds brought to the new world by the Spaniards. The result was a breed with the incredible scenting talents of a Bloodhound that also had strength and courageous tenacity. These characteristics made the Fila exceptionally well suited to protect the ranches and cattle of the Minas Gerais area against thieves and pumas.

Another common use for the Fila was on hunting forays to first track, then attack and hold the prey while the hunter caught up to take over. Actually “Fila” comes from a Portuguese word that means “to hold” or “to “secure”. Capturing runaway slaves was another way they were employed at one time.

The Fila is probably the only breed that for hundreds of years was selected specifically for their strong dislike of people they were not raised with. Even today in competition, temperament tests are run that require the dogs to attack without any prompting, to maintain self-confidence during the shooting test, and to clearly demonstrate a distrust of strangers.

There are two characteristics of the Fila that are noteworthy. First, the gait of the Fila is very unique to its breed. They move both legs on the same side of the body at the same time, rather than diagonally as all other dog breeds do. The other characteristic found in this breed is its leg and spine joints. These joints are loose allowing the Fila to change their direction suddenly and quickly, even running at a full speed.

Obviously like his ancestors, the English Mastiffs, Bulldogs and Bloodhounds, this is a large dog. He stands between 27 to nearly 30 inches tall at the withers. A small one weighs no less than 100 pounds. Certainly the female is slightly smaller yet they are still quite large as well. The female Brazilian Mastiff weighs in around 90 pounds, with a height that ranges between 24 to nearly 28 inches.

The coat of the Brazilian Mastiff is short and sleek. Colors include solid reddish tan, yellow, as well as black and brindled colors. It is interesting that Filas typically have a sad look to them while they are at rest. However, when they are active at the activities they were bred their appearance becomes energetic, alert and determined. It’s as if they are happiest when at work.

The Brazilian Mastiff is a bold, resolute and composed dog who shows self-confidence and courageousness, even in situations that are unfamiliar. They do not conceal their dislike of strangers but toward their human family they are usually very affectionate, gentle, loving and protective and are exceptionally loyal.

This is not a dog that just anyone can own. Even responsible owners will find the Fila challenging in certain situations. When you have a Brazilian Mastiff at home, having a weekly cleaning service or an occasional visitor in your home would require special consideration and management. As a result Filas need conscientious and cautious owners who recognize the need of early socialization of their puppy.
