FCI standard 225
Fila Brasileiro.
FCI 225: UTILIZATION 'Watch Dog'; Group 2, Section 2.1 Molossoid, Mastiff type; without working trial. Temperament: courage, determination, outstanding braveness; docile, obedient and extremely tolerant with children with its family; 'an unsurpassed guardian of properties, it also instinctively indulges in big game hunting and cattle herding'; natural aloofness towards strangers, especially in its own territory. CAFIB: courage, determination and valour; dislike of strangers is not hidden; in the city an unsurpassed property guard and in the country an excellent cattle dog and hunter of large animals; at shows the dog may not allow a stranger judge to touch it, and an attack on the judge is not to be faulted. Wikipedia: used as a guard dog, for cattle herding and big-game hunting, may be a companion; 'filar' means to hold or grab, so the name suggests a catch dog that bites and does not let go; bred on large plantations and cattle farms; taught to chase down jaguars and other animals; and in the eighteenth century, when slavery was legal in Brazil, used to return escaped slaves to their owners; first written standard 1946. Wikipedia: ownership is restricted by law in some countries; it lists Fiji, the United Kingdom, Norway, Australia, Hong Kong and Cyprus (illegal to own without a court exemption), Turkey (illegal to own and breed) and Trinidad and Tobago (classed as a dangerous dog). Check current local law..
Breed sets the odds. The parents set the dog. Every number here shows its source, its spread and how sure we are. Nothing on this page is a prediction about one dog.
The body
What the breed is built like. Registry standards give an ideal, not a range.
Height at the shoulder
Span covers FCI and CAFIB. No ideal printed.
Weight
Low is the printed minimum; no maximum printed anywhere, so high is blank.
Coat
Heat tolerance
Derived from a short dense coat (4). No measured data.
The work
What it was built to do in the field, and what a test or trial asks of it.
Role
Wikipedia's slavery-era use is stated as history. The CAFIB and FCI temperament lines are the breed standards' own words. The legal list is Wikipedia only (the government pages it cites were not opened); shown so a reader knows to check.
Primary game
Jaguar is named by Wikipedia alone.

How to read this page
Every value carries a label. Measured means peer-reviewed data on many dogs. Studied means peer-reviewed, smaller or indirect. Breed club means a club or registry states it. Editorial means expert opinion with no measurement behind it. Where two good sources disagree, both are shown and neither is averaged.
Published when the entry rests on the best information available from no fewer than three independent sources, checked by a second pass that did not write it. 2 sources on this page. Found something wrong? Tell us and the correction is logged with its date.
