Just to add here that according to CAFIB(brazilian regognition club for the fila) a real fila (fila its a lot more than phenotype) should show strong aversion against any stranger since puppyhood. Brazilians even have a special term for this called "ojeriza". So this friendly fila had a serious temperament fault compared to the authentic fila and according my personal oppinion, at least should not be bred, also they should try to improve his temperament with professional help. Soft dogs coming out of guard breeds just destroy the breed. People considering for large dogs as pets only whithout guard/protection duties to curry on, should strictly make their pick out of so many other large/giant breeds but never out of a GUARD breed and then try to change the instict and the temperament ,for many generations (sometimes hundreds of years) of both humans and dogs worked very hard to pass the trait and none has the right to degenerate it out of any guard dog and breed.
