Tails are usually docked short. There are two distinct coat types. The rough coat of the Brussels and Belgian Griffons is wiry and dense. The coat on the head is slightly longer than elsewhere, forming a fringe around the head and a beard. The smooth coat is similar to the Boston Terrier or English Bulldog with no wire hair allowed.
Color is as described above.
The average height of the Griffon is between seven and eight inches. The average weight is between six and twelve pounds.
