But both clubs (CAFIB and AMFIBRA) present themselves with the aim to preserve the pure Fila with the closest appearance of the old dogs.This big difference between the three standards is mainly due to an accusation of a scandal of crossbreeding at the dogs registered by the CBKC in the 70's, 80's and 90's and, consequently, the many changes made in the CBKC standard probable to include dogs with characteristics of foreign breeds, such as the English Mastiff, Great Dane and Neapolitan Mastiff.Paulo Santos Cruz himself, who even participated in the formation of the CAFIB for these same reasons and even presided over the club, published an article in 1979 explaining how to differentiate a pure Fila from a mixed one. The dedication and obedience of the Fila Brasileiro has found its way into the Brazilian saying 'as faithful as a Fila'.The Fila Brasileiro temperament is what characterizes the dog. The Portuguese word for their temperament is 'ojeriza', which directly translated into English means 'dislike' or 'distrust'.
