I have met quite a few. I was involved with many of the early breeders and I believe that I have more than my share of experiance with one. The differance between the Fila and other dogs is that a Fila WILL bite, and do real damage to a precieved threat. That means that you either have to be on top of the dog 24/7, or be willing to face a serious lawsuit in an urban enviorment. Filas react very quickly and they are faster, stronger and more agile than most of thier owners. They are also very vigilent and aware. It is easy for people to let thier guard down and with that breed you never can, ever. That is just a rough situation for the average dog owner. Other quick trigger breeds like the Komondorok & SRO also fall into this catagory. They are just 100% than what most have been accostomed too. I believe it is best to rely on the typical, not count on the atypical. Most potentital owners have no business with a Fila. Just like most hunters have no business with a howitzer.
