The Fila paces. Its FCI standard calls this two-beat movement, with both legs on one side moving together, the principal gait characteristic; a Fila without it is disqualified. The body rolls with the movement, known as a camel pace.

A Brazilian guard dog
The standard describes a guard dog with instincts for hunting large game and working livestock, but provides no historical summary. English Mastiffs, Bloodhounds and Bulldogs are commonly considered ancestors. A mitochondrial analysis found a more complex picture, although based on only one dog (Fontenelle et al. 2026). Useful comparisons include the Mastiff and Bloodhound. The FCI has recognised the Fila since 1960.
Loyal within the family, unwelcoming outside it
Courage, determination and bravery come first in the standard. Docile with family, exceptionally tolerant with children, with proverbial loyalty. Natural reserve towards strangers, especially on home ground, must be controlled even in the show ring. Aggressive dogs are disqualified. Because the breed appears on regional restricted lists, check beforehand what permit or assessment applies where you live.
Loose skin as a breed feature
Thick, loose skin across the body is a major feature; its absence is disqualifying. It forms dewlaps at the neck. The standard explicitly does not regard drooping eyelids as a fault, so request eye findings for both parents. Cropped ears or docked tails are disqualifying.
Health: scarcely any data
We found no Fila study providing reliable lifespan or disease figures. The large UK life-expectancy analysis excludes the breed for lack of data (McMillan et al. 2024). Without data, you must rely on parents’ hip, elbow, heart and eye findings.
Unexpected movement
Calm in disposition, yet surprisingly fast at a gallop, says the standard. Long, steady walks and a job on the home property suit this dog; crowded city life less so.
Who the breed suits
Highly experienced people with fenced land, little visitor traffic and willingness to manage visitors consistently.
Who should look elsewhere?
First-time owners, rented flats, open houses with many guests and anyone seeking a café companion.
Start assessing whether such a territorial guard dog suits you through the breed quiz; our book “Which Dog REALLY Suits You?” (book in German) offers greater depth. For the start of puppyhood, there is the free Puppy Starter Pack. If your Fila is already guarding your property, explore dog portraits from your own photo, perhaps as a magazine-cover canvas.
