The Brussels Griffon is a small and charming toy dog breed known for its unique appearance, lively personality, and affectionate nature. These dogs typically weigh between 7 to 12 pounds and stand around 7 to 10 inches tall at the shoulder. Brussels Griffons have a distinctive, almost human-like expression, with a domed head, large, dark eyes, and a short, broad muzzle. They come in two coat varieties: smooth and rough. The rough-coated variety has a wiry, tousled coat, while the smooth-coated variety has a short, glossy coat.
