The Belgian Mastiff, also known as the Chien de Trait Belge, Mâtin Belge and Belgian Draught Dog, is a breed of mastiff-type dog from the Low Countries that was used as a draught dog.
The Belgian Mastiff is a large, powerful dog that stand between 69cmand78cmcm (27inchesand31inchescm) and weight between 45kgand50kgkg (99lband110lbkg). The breed is muscular and heavy-boned with a large head and thick neck. Their tails are typically docked to prevent them from being damaged whilst pulling carts. The Belgian Mastiff's coat is short, smooth and loose fitting; they are typically fawn or brindle in colour, with dark masks and white markings also known.
In character, the Belgian Mastiff is described as a tireless worker with strong protective instincts; they are not known to be particularly friendly to anyone but their masters.
Little is known about the Belgian Mastiff's ancestry except that it is believed to be descended from French mastiffs introduced to the Low Countries at some point. The breed was seen throughout Belgium and the Netherlands pulling carts, often delivering milk, butter, meats and vegetables.
The Belgian Mastiff's role as a draught animal became increasingly obsolete throughout the 20th century and the ravages of the two world wars further took their toll on the breed. It is believed it became extinct in the second half of the 20th century. Prior to its extinction, the breed was recognised by the Société Royale Saint-Hubert and the Fédération Cynologique Internationale, in recognition of its supposed extinction the Fédération Cynologique Internationale has placed the breed on its suspended breeds register and the Société Royale Saint-Hubert stated it "may be extinct"; holding out hope that surviving specimens may be found, they maintain the breed's listing.
