Rather firm. Upper lips moderately hanging, they join under the nostrils to form an inverted “U.” Pigmentation matches color pigment of dog, Dogs with black pigment have black lips, gray pigmented dogs have gray lips.
Bite: Up to a 1/4 inch undershot means there can be as much space as the width of a pencil between the upper and lower incisors. Often that space appears greater than it is. Rarely does a Corso with a scissors bite possess a correct muzzle. However, at this stage of the breed's evolution, subjects with level and scissors bites are necessary in breeding programs. Undershot is a progressive characteristic, and the level and scissors bites help keep it in check. Slightly undershot (no more than 1/4 inch) and level preferred, scissor bite is acceptable if parameters of the head and muzzle are correct. The incisors are firmly placed on a straight line. Dentition is complete with no more than two missing teeth.
Neck, Back and Body: Neck: Slightly arched, flowing smoothly into the shoulders with a small amount of dewlap. The length of the neck is approximately one third the height at the withers. Body: Depth of the ribcage is equal to half the total height of the dog, descending slightly below the elbow. It's important that the floor of the ribcage, when viewed from the side, sit close to the elbow. If too far above, the dog is leggy, top heavy and lacks mass. Too far below, and the front is overdone and is not balanced with the rear, compromising agility. Ribs are long and well sprung. Moderate tuck up. Chest: Broad, well muscled, strong forefront. Back: Wide, strong, muscular. Highest part of shoulder blade slightly rising above the strong, level back. Loin: Well-muscled, and harmoniously joined to the back. Croup: Long, wide, slightly sloping. Rump should be quite round due to muscling. Tail: Tail set is an extension of the backline. All too often in the Corso we see tail sets that are not an extension of the backline, but appear to come out from the rear, three inches below the back. This is an indication that the pelvis is titled too steeply and therefore drastically inhibits the back reach. It is thick at the root with not much tapering at the tip. When not in action carried low, otherwise horizontal or slightly higher than back, not to be carried in a vertical position, it is docked at the 4th vertebrae. Natural tails are accepted, though not preferred. In the case of natural tails, the tip reaches the hock but not below. Carried low, it is neither broken nor kinked but supple. Hanging when the dog is in repose; generally carried level with the back or slightly above the level of the back when the dog is in action, without curving over the back or being curled.
Forequarters: Strong and muscular, well proportioned to the size of the dog. Straight when viewed from the front or side, height of the limb at the elbow is equal to 50% of the height at the withers. Shoulders: Muscular, laid back. Laid-back shoulders are very important, allowing the forearm to extend for good reach. Unfortunately we see far too many straight shoulders, forcing the dog to take short steps and causing a "prancing pony" gait -- not the correct, elongated trot. Upper arms: Strongly muscled, with good bone, powerful. Elbows: Held parallel to the ribcage, turning neither in nor out. Forelegs: straight and with good bone well muscled.
Pasterns: Almost straight, strong but flexible. Feet: Round with well arched, toes (cat like).Lean hard dark pads and nails except in the case of white toes. Front dewclaws: Can remain or be removed, if left intact should only be a single dewclaw on each leg. Hindquarters: As a whole, they are powerful and strong, in harmony with the forequarters. Thighs: Long, wide, angulated and well muscled. Stifle: Should be moderately angulated, The best way to determine correct (moderate) angulation is to place the hock so it forms a 90-degree angle with the ground and extend the tail (which is docked at the fourth vertebra). There should be a plumb line from tip of tail down through the hock to the back of the foot. strong. Legs: Strong bone and muscle structure. Hocks: wide set, thick and clean, let down and parallel when viewed from behind. Rear pastern: straight and parallel. Rear dewclaws: Any rear dewclaws are removed. Hind feet: Slightly more oval shaped and less arched toes than the front feet.
Coat: The coat is short, stiff, shiny, adherent and dense with a light undercoat that becomes thicker in cold weather.
Color: No color is preferred over another. Each has historical and functional significance. Acceptable colors are black, lighter and darker shades of gray, lighter and darker shades of fawn, and red. Brindling is allowed on all of these colors. Solid fawn and red, including lighter and darker shades have a black or gray mask; it does not go beyond the eyes. There may be a white patch on the chest, throat, chin, backs of the pasterns, and on the toes.
Gait/Movement: The movement is free flowing, powerful yet effortless, with strong reach and drive. As the dog accelerates, the feet converge towards a center line of gravity in a near single track. When viewed from the side, with minimal roll and bounce.
Temperament: The Cane Corso as a protector of his property and owners is unequaled. Intelligent he is easily trained. Noble, majestic and powerful his presence is impressive. He is docile and affectionate to his owner, loving with children and family.
Disqualifications: It is my opinion that the fancy should concentrate on what a Correct Corso is, not what it isn't. Too much emphasis placed on te DQs alone will not create a good Corso, only a dog without those traits.
