The Brussels Griffon began as a scruffy stable dog in Brussels, where coachmen kept them to catch rats. Crosses with Pugs and toy spaniels later gave the breed its domed head, big dark eyes, undershot chin and sturdy, square little body. Adults usually weigh 7 to 12 pounds and come in a wiry rough coat with a beard or a short, glossy smooth coat.
Griffons are alert, sensitive and a little full of themselves, and many pick one favorite person. In a Scottsdale home, that often means a shadow who follows you from room to room and announces every visitor. Rough coats need periodic hand-stripping, smooth coats are easier, and the flat face calls for extra care when the temperature climbs. Dogs vary, so a Griffon's own habits matter more than the breed label.
