Although pitting dogs against one another continued to be a common pastime in rural areas, the breed was unable to be sustained on its own and numerous matings with other fighting and hunting dogs ensured the disappearance of the Viejo Perro de Pelea Cordobas in its true form. While it vanished, this impressive bulldog has not been forgotten and has been the inspiration for a few modern breeds, including the Venezuelan Fighting Dog, the Dogo Guatemalteco, the Yankee Bullterrier and of course, the great Dogo Argentino, for whose creation it provided the very foundation. Wide-chested, broad-shouldered and muscular, this powerful Molosser was a strong and agile worker. The ears were usually cropped, but unaltered examples existed as well.
Even though the most valued specimens were pure white in colour, many examples were yellow, fawn or red and there were reportedly even some multicoloured dogs to be found in the pits. The average height was around 24 inches.
