The hardest tempered, most maniacal fila, with no regard for for human life, lock up the women and children, and the men as well...was a black female. She was as calm and lay around as any dog I have ever seen. When we got her as a pup, about 12 weeks, my son was the only would that could touch her. A day or so later it was me, and then after three or four days it was my wife. A good friend's daughter. But that was it. This bitch spewed death to any and all. This is the bitch we set up the 'break in' at my house. She delivered like nothing I had ever seen. She amped up every time the pressure was increased. And again she was black. Her only shortcoming was that once she was amped up there was no release for her, even after the 'attacker' had fled it was an hour or so and she was still 'ready'. Jacked up to no end. This is mentally unhealthy for the dogs. The entire purpose of the tennis ball for the service type dogs. Dogs need a release. Defensive driven dogs like the Fila do not have that, thus even when they have the temperament and it is worked up, and there is no release, eventually there are nerve issues, or lack thereof. Because of this she aged quickly. She was old before her time. She could go from laying on the couch to pshyco in a blink, but would take lots of time to unwind.
My favorite line in these dogs is that black dogs do not have temperament because they are black and there is no such thing as a black Fila. Until I figured out the toll it was taking on her I hauled her to a number of shows. And she was open to the world. Get your money and the decoy will decide who is the hardest biter, the most intense fighter and who would stay the longest. On the internet I had numerous offers/challenges. At the shows and gatherings the deal was off once she did her thing. And she was black. I mean slick as glass, black as onyx, shiny black. Black. If she were still around I could show anyone that a black dog can get it done and does not have to come from Brazil. S
