The Brussels Griffon started out as a scruffy stable dog in Belgium, kept by Brussels coachmen to catch rats. Later crosses with Pugs and toy spaniels gave the breed its domed head, short face and big dark eyes, along with an expression people often call almost human. Griffons weigh roughly 7 to 12 pounds and come in a wiry rough coat with a beard or a short, glossy smooth coat.
Most Griffons are alert, sensitive and strongly attached to their people, often picking a favorite. They can be opinionated and vocal, and many dislike long hours alone or rough handling from small children. The flat face calls for care in heat, and rough coats need regular hand-stripping. In a compact city like SF, that adds up to a small dog with a big personality and very little interest in being left home.
