About the Córdoba fighting dog
The Córdoba fighting dog was a type of dog indigenous to Córdoba, Argentina, that resulted from crossbreeding old mastiff types of unknown pedigree. They were purposely bred for the sport of dog fighting until the early 20th century. They became extinct after dog fighting became illegal in Argentina in 1954.
