Banned dog breed:Dogo Argentino

First bred in Argentina in 1928, the Dogo was taken from the now extinct Cordoba Fighting Dog, which was mixed with various other breeds, including the Great Dane, Dogue de Bordeaux and Irish Wolfhound. Breeder Antonio Nores Martinez developed his dog as a big game hunter, taking on such dangerous prey as the mountain lion. Although it was not its original purpose, the Dogo has also been used for fighting. Generally weighing in at just under a hundred pounds, it is solid white and resembles a larger Pit Bull. The Dogo is banned in at least 10 countries, including Australia, New Zealand and Portugal.
