Original Fila Brasileiro

The Original Fila Brasileiro (OFB) or Old Brazilian Fila is a rare working farm dog breed from Brazil. The remaining Old Fila dogs preserved on farms in the interiors of Brazil are being gathered to become a formalised breed. The Original Fila Brasileiro is recognized by the SOBRACI in Brazil, and despite the similar name, it is a breed apart from the modern Fila Brasileiro.
The term "Fila dog" has historically been used as a description of the duty or purpose of a dog. In Portuguese the verb filar means "to grasp strongly with the teeth".
The Fila Brasileiro is considered dangerous and is banned in England and Wales.
