Dogman, I'm not sure anyone is suggesting that one attempt to breed a basic known trait out of any dog. Perhaps I am just not reading the posts as you are, but all I see is a discussion about the breed type, and how "Backyard Breeders" could make this relatively unknown Breed extremely dangerous.
I have to concur that if one wishes a more docile dog, then one should select a breed designed for that, and not attempt to take a dog that is bred to protect, at any and all costs, and try to change that.
It is alarming, and we should all be concerned, that for those who don't bother to do their research, and don't bother to learn and train their dogs properly, that this Breed could be potentially hazardous to any community, which would only be the fault of the humans.
Clearly you are passionate about this breed, and this section is here so that others can learn about different Breeds. Do you own a "Fila"? If so, perhaps you could post some photographs and talk a little about what you do know about the breed, personally as no one here, with the exception of one, actually owns one of these dogs.
Is that a photograph of you as your "profile picture"? Perhaps you are that "tough guy" to which Kian referred. Do you work with dogs? We all wish to learn, and perhaps you have things you could share of value. So far though, your approach is most off-putting.
