here in Brazil we have the "Fox Paulistinha" , or world known as Brazilian Terrier, is a Brazilian Breed , originated in the country side of São Paulo state , people from são paulo are Paulistas , like texans from texas , and paulistinha would be something like "little paulista" ...
the breed started with some Jack Russels brought by europeans imigrants in the 1800's , mixed with some pinchers , beagles , and god knows what else in the farms , but since the 1900 is a comom breed , much apreciated by farmers in São Paulo , , and since 1950 is wrold reconized breed ...
