The Dogue de Bordeaux, Bordeaux Mastiff, French Mastiff or Bordeauxdog is a large French Mastiff breed—and one of the most ancient French dog breeds. The Bordeaux is a very powerful dog, with a very muscular body. This brawny breed has been put to work in many different capacities, from pulling carts and hauling heavy objects, to guarding flocks and, historically, the castles of the European elite.
The Dogue de Bordeaux was known in France as early as the fourteenth century, particularly in southern France in the region around Bordeaux. Hence, the city lent its name to this large dog. A uniform breed type of the Bordeaux Dog did not exist before about 1920
According to the Federation Cyniologique International, the Dogue de Bordeaux “assumes guard with vigilance and great courage, but without aggressiveness”. It is “very attached to the master and very affectionate with children”.
