In the 1880s, a veterinarian named Dr. Jose Leite Pacheco attempted to make a standard for this breed. He intended to make the name ‘rabo torto‘ as the breed’s official name within the FCI. The name he tried to give the breed translated to ‘curled or twisted tail’. However, FCI never accepted as it was already an endangered species at that time.
