The Brussels Griffon is a compactly built toy dog, descended from the Belgian Street dog and Affenpinscher. This alert and unusually intelligent dog has a wiry red-brown coat, fringed around the eyes, nose, chin, and cheeks. Its turned-up nose, dark eyes, and prominent chin are characteristic of the breed. Small size dogs usually weigh no more than 7 pounds and large size dogs do not exceed 11 or 12.
