I found this on a website. I voted No.

Some breeders breed the Fila to have a temperament in which they say is more like the original Fila Brasileiro temperament. One breeder who claims to breed to the original Fila type states, "You cannot socialize a Fila to like people. You can obedience train them so that you are in control, but you cannot socialize them to like people. A Fila WILL attack a stranger. Period. If they have the proper temperament, they WILL. "Ojeriza" translates to "Hatred and loathing of strangers". You do not make them mean and vicious... they ARE... and there is no doubt about it. They are not a dog for a person who has an active social life."
