Griffs, as they are known, weigh in at about 5 to 15 pounds and stand at 9- to 11-inches tall. They served as both work dogs and noble companions in their native Belgium, and they are the little old men of the tiny dog world with their expressive bearded faces and big eyes.
They come in four colors — red, black-and-reddish brown, black and tan, and black, and they can have either a smooth or rough coat. They are stocky, confident and easy to train, but like Chihuahuas, they are fragile when it comes to rough play. Plus, they can get lonely — they do best in groups with other dogs or in a home with someone who’s always in attendance.
