As he was in need of cattle drovers, and he found the Filas too heavy for the work, he crossed his stock with "German Boxers", and declared that he was pleased with the new product he got. Another breeder from the 50's was Pedro Ribeiro Junqueira de Souza, of Fazenda do Engenho, in Silvestre Ferraz, currently Carmo de Minas and São Lourenço. He started to breed Filas in 1920 with Filas brought from Cristina, near Itajubá, by his brother in law. He selected two different lines: one dark brindle, which sometimes produced gray and blue colors of medium size, very strong with massive heads and lots of dewlaps. The other one was of very large yellow dogs with plenty of dewlaps. From this yellow color line, Dr. Paulo Santos Cruz got a female registered in 1958 under the name of Fera do Parnapuan (BKC register No 16785) which bred to the famous Tamoyo de Parnapuan brought from Conselheiro Lafayete, gave birth on April 23, 1959 to one of the best Parnapuan litters due to their uniformity, size and beauty, in accordance to Mrs.Antonieta Santos Cruz. In this litter was the famous Orixá de Parnapuan, very heavy, 79 cm (31 inches) weighing 94 Kg ( 188 lbs ) besides another nine siblings, among them the black Fila Ogum de Parnapuan, who was kept by Dr. Santos Cruz for reproduction. Unfortunately this dog died at an early age. By the way, as I have already mentioned, Fera de Parnapuan is one of Camping dogs ancestor. Another well know breeder having Filas from the São Francisco valley was João Accioli from Tapiocanga Kennel (1949). It has been recorded that his family, Martins Soares, owned Filas since the end of 1.800 in Neópolis, at the Fazenda Varzea Nova and Engenho Cadoz. They were called "cabeçudos" at that time. Later on, the family and dogs moved to the state of Goiás. Mr. Accioli theory is that the "cabeçudos" were introduced by the legendary "Bandeirantes" (from São Paulo) in Goiás. "Bandeirantes" were explorers from São Paulo traveling through the wild country looking for slaves, gold and diamonds, opening new frontiers and starting settlements in inhabited areas from Brazil. They were in need of Filas during their long expeditions in order to catch Indians and to protect their mules from jaguars. Mr. Accioli tells that Caixeta family was also a great source of Filas between Pires do Rio and Orizona. They were dark brindles in his majority. In 1923 Mr. Accioli saw yellow and black Filas in the ranch owned by the Gonçalves family. The dog that most impressed him was Chibante, a large dog with a very massive head, black with white owned by Mr. Manoel Gonçalves. He tells a story about Chibante bringing down a furious bull that refused to enter the corral threatening the ranchers’s lives. Chibante was also the pack leader and chief guardian of the ranch. He marked his territory in a triangle: Main house, yard and corral. He would not follow the ranchers when traveling with cattle. This work was done by the "atravessados", mixed Filas with hound dogs, who were lighter and preferable for long distances. Mr. Accioli started his kennel with dogs from Santa Cruz, Goiás, and his best dog was Protetor de Tapiocanga, a brindle with white chest and green eyes, registered under KCP # 1585 on January 15, 1952. This dog had excellent litters, very aggressive, some of them black, with white chest and brown patches. He closed his kennel in 1971.
