Brazilian bullmastiff

GENERAL APPEARANCE: Compact structure for its size, of great physical strength, robust, an active, elegant, medium-sized and proportional dog, giving the impression of power.  The breed must have variations between the “Bulldog” and the “Mastiff” style, with lighter matrices and heavier studs, preferably.  


The rustic handling combined with a strong  selection pressure in beef and dairy farms in Minas Gerais, formed the current lines of Bullmastiff Brasileiro.  The individuals chosen were those of the breeds: Dogue de Bourdeaux, Bullmastiff Ingles, Rottweiler, American Pit Bull Terrier, crossed with traditional Filas Brasileiros found in Fazendas Mineiras, during the period of formation of the breed between 1988 and 2005. The individuals selected after the crossing with Filas, provided genetic material for the task of rescuing typical specimens called: Bull & Mastiff's that existed in several places in Europe and also in Brazil during the period between the 19th century until the end of the 20th century.

The breed was developed for working on farms, and its conformation is flexible, allowing selection based on temperament. The temperament and the combination of elegance, softness and loyalty are the most desirable characteristics of the breed.

Country of Origin: Brazil.

BEHAVIOR AND TEMPERAMENT:  born guardian. Intelligent and docile dog with the people of the house. It must possess extreme courage and show submission to discipline before its owner. Must be friendly with other animals and dogs, but fearless when provoked or on command. He likes to be with the whole family, especially with children, but he is a “few friends” dog, especially when the owner is not at home. As a guard dog, the objective is to defend the Family and as a herdsman, it is intended for general use on cattle farms, having the ability to gather a herd, bringing them to the corral without biting or knocking them down. It must be extremely agile and intelligent, defending cattle from possible predators.  


HEAD/SKULL :  The head should be heavy, broad and robust. It is the most striking conformational feature in the breed.  The length of the muzzle must not be the same as that of the skull, it must be slightly shorter, but without exaggeration.   The ideal head is a middle ground between the “Bulldog” style and the “Mastiff” type.


Snout:  black mask is  desirable.

Truffle:  Black, or red, preferably following the coat color.

Jaws and Teeth: Torques with a strong and powerful jaw is the  desirable. The heavy bite is typical of the breed and should be a major factor in the selection of sires and dams.  

Eyes: Oval or almond shaped, slightly rounded, similar in color to the coat.  

Ears : Medium, hanging, with thick skin. Looking from the front the "closed V" shape when in attention is the  desirable, being  wide at the base, forming a triangle in the middle, in the shape of a V.  implantation of ears in line with the eyes is desirable without exaggeration up or down.

NECK : Thick, strong, with throatiness.


TAIL:  Saber-shaped, without deviating to the sides. Brought low when at rest and in flag when alert or in motion.



PREVIOUS :   The shoulder set forelegs should be visibly muscular denoting power in conjunction with the  chest,  which should be broad and with good chest depth.  The paws must be large and proportionate to the size of the dog. Feet with open and or spread toes and with incorrect angulations is a serious fault.

HINDQUARTERS : The hindquarters, especially the lower back, should be well muscled with shapely legs. Correct angulations in the hip and hock region. Strong and rounded croup.

  • DRIVE :  The gallop is of great speed and elasticity. When trotting, it should appear smooth, sophisticated and charming.
