The Dogo Sardo is a very muscular and athletic working dog, differing from the Cane Corso in some facial features, having a longer muzzle and tighter skin. Some rural dogs have fairly lupoid muzzles, but their purity is questionable. The body is lean and strong, with a powerful neck and sturdy legs. The ears are usually cropped, sometimes completely removed, while the tail can be both docked or left in its natural state.
The coat of the Canis Pertiatzus is short and smooth, usually red, grey, black or brindle in colour, but some working specimens are also common in other shades, as well as having slightly rougher coats. This rugged dogge rarely exceeds 24 inches in height, but since there are no set size limits, a variety of heights can be encountered.
