An adult dog weighs between 20 and 35 kilograms (44 and 77 lb). This breed, relative to its size, is heavier-boned than any other.This breed, like its ancestor the Bloodhound, has a hanging skin structure, which causes the face to tend to have a sad look; this, for many people, adds to the breed's charm. Because Bassets are so heavy and have such short legs, they are not able to hold themselves above water for very long when swimming, and should always be closely supervised in the water. Bassets are large, short, solid and long, with curved sabre tails held high over their long backs. The previous FCI standard described the characteristic skin of the Basset, which resembles its ancestor the Bloodhound as 'loose'.
