It was a Neapolitan Mastiff that played the part of “Fang”, Hagrid , the half-giant’s dog in the Harry Potter films.
The large mastiff-type head is complemented with an equally large body in which the musculature is barely hidden by thickly folded skin.
The Neapolitan Mastiff is thought to be the direct descendant of the ancient Roman Molossus used for both war and the bloodthirsty arena.
In essence this dog was bred to be a capable killer making it a popular guard dog and defender.
This is recognised by the fact many of these breeds are banned in countries throughout the world.During the days of slavery the Fila was allegedly used to return fugitive slaves, unharmed, to their masters. What separates the Fila from other big mastiff type dogs is its temperament and potential for aggression.
