The Dogue de Bordeaux was once used as a ferocious fighting dog, trained to attack bulls, bears, and other dogs. Although today’s breed appears as intimidating as its ancestor, it is a calm and gentle creature, loyal to its master and patient with children. The Bordeaux has a good and calm temperament. It is extremely loyal, patient and devoted to its family. The Bordeaux may be fearless and confrontational with strangers, but he is a first class guard and watchdog. This breed needs a calm, but firm owner, who displays a natural authority over the dog - one who is confident and consistent.
