Brazilian Mastiff

Famously described as a combination of a mastiff and a bloodhound, the Brazilian mastiff or Fila Brasileiro, are quite large, with heights ranging roughly 24 to 30 inches at the shoulder. They weigh anywhere from 90 pounds up, with the female dogs weighing less than their male counterparts. Their coat colours vary from yellow to red to black.

Historically, these dogs have been used for hunting animals and even slaves, as well as defending ranches from cattle rustlers and wild animals. They did not usually kill the target; rather they pursued, tackled and detained the quarry then waited patiently for their owners to recover the prey.
This breed is more agile compared to the other mastiff breeds. This may be due to the fact that their joints are actually loose, allowing them to swiftly change direction even when they are moving at top speed. These dogs are also not as likely as those of other mastiff breeds to become obese.

Part of what makes the Brazilian mastiff so interesting is the fact that its mistrust of strangers is its most prized trait. At dog shows, it is actually a point for the dog if he attacks the judge. But like other types of mastiffs, Brazilian mastiffs are very loyal and gentle towards their owners and their families. This loyalty manifests through a very hostile approach towards strangers and any sensed threat towards their owners. They can suddenly attack the intruder without waiting for their owner’s command so it is prudent to keep them away from house guests.
