The Bouvier des Flandres was developed in the nineteenth century as a farm dog in the northern hills of France and Belgium. Mastiff and Sheepdog elements may be in their background but we can only speculate. Their double coat, which protects them in all weather, is ideal for their traditional jobs of herding, pulling milk carts, and police work. Bouviers are big, males often reach 100 pounds, powerful, agile and very intelligent. A serene disposition and total devotion to their family are as much a part of Bouvier nature as their rugged appearance.
