The Cordoba Fighting Dog originated in Córdoba, Argentina. They were noted for their willingness to fight to the death, and their high pain tolerance. The breed had such strong aggression toward other dogs that the males and females would rather fight than mate. In addition, many members of this breed died in the dog fighting pits, contributing to the breed's extinction.
The Cordoba was capable of hunting in a small pack of a male and female, otherwise they were likely to turn on their pack-mates.
