The Buldogue Campeiro (litteraly, "rural bulldog"), also called the Brazilian Bulldog, is an extremely rustic working dog. It descends from the ancient English Bulldogs brought to the Rio Grande do Sul and Santa Catarina states in south Brazil by the European immigrants since the 16th Century. Through the decades, the name, derived from the english "bulldog", was adapted to the portugese language, which brought up words like "burdogue", "bordoga" or "buldogue pampeano".
In southern Brazil, bulldogs were frequently used to capture "wild" cattle, extensively raised in the hostile field environment nearby native forests, were they were used as shepherd dogs as well as bull controllers throwing and holding any escaping cattle. These dogs participated in long journeys to capture lost cattle and were mainly maintained in slaughterhouses where they were especially used to hold furious bulls whenever necessary or when cattle, but also pigs, were to be led from the fields and to the slaughterhouse. These very versatile dogs were characterized by a very well balanced nature between the aptitude to act as a guard and a natural prey instinct. They used to live and work together in packs of five Bulldogs or more.
Working Bulldogs developped through natural selection, as the very low-sized animals were disadvantaged when traveling long distances and when immobilizing bulls by pulling and holding them. On the other hand, the excessively tall ones resulting from crossing with other breeds often lost their natural prey instinct and their precision of movements, which made them especially vulnerable to horn and backward kicks.
Until recently, the "Buldogue Campeiro was only used on farms and around abattoirs until Mr. Ralf Schein Bender started a breeding program in order to rescue this rustic breed from extinction. He started looking for the last specimen of these bulldogs in the mountainous regions, in the hinterland of the Rio Grande do Sul, in the border regions and the nearby state of Santa Catarina. These rescued bulldogs were selected and submitted to an intensive and responsible breeding program in order to maintain those original bulldog features from their ancestors alive. These included not only the external morphological characteristics but also temperament and physical aptitude to resist exhaustion when travelling long journeys controlling bulls in the field. In his search Mr. Bender talked to many people that had first hand knowledge about the Bulldog, and he was told many stories from old people who could still remember the Buldogue Campeiro. After collecting the few original remaining Campeiro Bulldogs still alive, Mr. Bender saw the necessity to introduce blood of the modern English Bulldog, with the purpose to reinforce the ideal features of the Campeiro and to save the breed . In his breeding program Mr. Bender always only selected for further breeding those specimens that had most of the characteristics from the Campeiro.
