This breed is originally from the province of Córdoba, Mediterranean region of the Argentine Republic. Its creator was Dr. Antonio Nores Martinez, eminent and active surgeon born in Córdoba in 1907 and died in 1956. His work started from the methodical crossing of the “Old Dog of Fight of Córdoba”, an example of great power and strength, product of the crossbreeding that was then done between dogs of the Bulldog and Bull Terrier breeds. He chose completely white specimens for the creation, without prognathism, with a heavy head and a long snout. After an intense and thorough selection and character study in several generations, he achieves his goal by forming several families, always starting from that “Old Dog of Fight of Córdoba”, which initially crossed with the English Bulldog, Great Dane, Mastiff of the Pyrenees, Bull Terrier, Boxer, Pointer, Dogue de Bordeaux and Irish Wolfhound. In 1947 the breed was already created and stabilized geno and phenotypically; for that same year the breed standard is presented at the Hunters Club of the City of Buenos Aires. Its strength, tenacity, smell and bravery make it unmatched among pack dogs for hunting wild boar, peccaries, cougars and other predatory species of agriculture and livestock that inhabit the vast and heterogeneous regions of Argentine territory. This is the traditional activity for which Antonio Nores created this breed. In 1964, it was recognized as a breed by the Argentine Cynological Federation and by the Argentine Rural Society, which opened their “Genealogical Registry”, starting their registration. Recently, in 1973, the breed is accepted by the FCI (International Cynological Federation).

Complete dentition is recommended. The bite is scissor (that is, the caudal face of the upper incisors touches the cranial face of the lower incisors, covering them), accepting in forceps (or pincers, that is, the upper incisors are in contact tip to tip with the lower incisors).
