Farmers in Flanders, the lowlands spanning Belgium and northern France, relied on the Bouvier des Flandres to drive cattle, pull carts and watch the farmyard. The breed served as a messenger and ambulance dog in World War I and nearly vanished in the devastation, rebuilt afterward from a few surviving lines. Today's Bouvier is a big, square, powerfully built dog with a tousled, harsh double coat, a heavy beard and mustache, and colors from fawn to black, including brindle and salt and pepper.
The breed standard describes a steady, resolute and fearless dog, and many Bouviers are calm, loyal family guardians that keep a watchful eye on strangers. They are intelligent and capable of serious work, so they need consistent training, early socialization and a real job or sport. The coat needs substantial weekly grooming and regular trimming, which adopters should budget time or money for.
