There are numerous hypotheses about the origin of the Dogue de Bordeaux. It may be descended from the Greek and Roman Molossus, from mastiffs brought to Europe by the Alans, from the dogs of Aquitaine or from Spanish dogs from Burgos. The breed has served as a war dog and flock guardian, and as a combatant in dog gladiator sports where they were pitted against bulls, bears and other dogs.
