Breed History:

The Fila Brasileiro is a powerful mastiff-type breed developed in Brazil during the 17th century. It was originally bred to track, capture, and hold large prey such as jaguars and runaway slaves on colonial plantations. The breed descends from a mix of European breeds like the English Mastiff, Bloodhound, and Bulldog, combining tracking ability, tenacity, and guarding instincts.

"Fila" means "to hold" in Portuguese, reflecting the dog’s instinct to capture but not kill. Over time, the Fila became prized as a guardian of farms and estates, known for its deep loyalty to its owner and intense suspicion of strangers. Though controversial for its guarding nature, it is considered a national treasure in Brazil and is recognised by the CBKC and FCI.
