The Dogue De Bordeaux is a giant dog that stands 58 to 69 centimetres at the withers and weighs 125 to 150 pounds. It has a powerful and muscular look, and although it is heavy, it is quite athletic and agile when necessary. This massive dog has an exceptionally large head with short muzzles. Its skin around the face and neck is loose, which forms deep wrinkles. It has a moderately prominent forehead, small ears that are a bit darker than its coat, small oval eyes, and powerful undershot jaws. It has a serious, imposing and intimidating expression.
The Dogue has a short, fine coat that is soft to the touch. It has a loose-fitting and thick skin without excessive wrinkles. It has self-coloured coats, which according to KC standards should be in all shades of fawn, from mahogany to Isabella. Chocolate is considered undesirable, so are white patches on the head or body. In addition, the breed can have any of the three masks: no mask, black mask and brown mask.
Thanks its short coat, it does not have overly demanding grooming needs. It requires weekly brushing to keep shedding under control, as well as regular wiping of its facial wrinkles to avoid bacteria build-up, and its mouth because it drools a lot. Its ears need to be cleaned at least twice a month to avoid wax build-up. Completing its grooming routine are regular tooth brushing, nail trimming, as well as skin inspection for spots and ticks.
