Genotype & Phenotype
Genotype is the genetic makeup for the breed.
This is either the powderpuff gene or the hairless gene. This is what defines them as one or the other.
Phenotype is what you can physically see on the dog.
For a powderpuff, you can visibly see 2 coats of hair coving the whole body; the thin guard hairs and the soft undercoat.
For a hairy hairless, you can visibly see thin guard hairs on parts of the body that can vary from all over to just a few areas. There will be no soft undercoat.
For a hairless, you can visibly see thin guard hairs on the head, neck, tail and feet.

Chinese Crested- AKC Breed Standard
A toy dog, fine-boned, elegant and graceful. The distinct varieties are born in the same litter. The Hairless with hair only on the head, tail and feet and the Powderpuff, completely covered with hair. The breed serves as a loving companion, playful and entertaining.
Size, Proportion, Substance
Size - Ideally 11 to 13 inches. However, dogs that are slightly larger or smaller may be given full consideration. Proportion - rectangular-proportioned to allow for freedom of movement. Body length from withers to base of tail is slightly longer than the height at the withers. Substance - Fine-boned and slender but not so refined as to appear breakable or alternatively, not a robust, heavy structure.
Expression - Alert and intense. Eyes - Almond-shaped, set wide apart. Dark-colored dogs have dark-colored eyes, and lighter-colored dogs may have lighter-colored eyes. Eye rims match the coloring of the dog. Ears - Uncropped large and erect, placed so that the base of the ear is level with the outside corner of the eye. Skull - The skull is arched gently over the occiput from ear to ear. Distance from occiput to stop equal to distance from stop to tip of nose. The head is wedge-shaped viewed from above and the side. Stop - Slight but distinct. Muzzle - Cheeks taper cleanly into the muzzle. Nose - Dark in dark-colored dogs; may be lighter in lighter-colored dogs. Pigment is solid. Lips - Lips are clean and tight. Bite - Scissors or level in both varieties. Missing teeth in the Powderpuff are to be faulted. The Hairless variety is not to be penalized for absence of full dentition.
Neck, Topline, Body
Neck - Neck is lean and clean, slightly arched from the withers to the base of the skull and carried high. Topline - Level to slightly sloping croup. Body - Brisket extends to the elbow. Breastbone is not prominent. Ribs are well developed. The depth of the chest tapers to a moderate tuck-up at the flanks. Light in loin. Tail - Tail is slender and tapers to a curve. It is long enough to reach the hock. When dog is in motion, the tail is carried gaily and may be carried slightly forward over the back. At rest the tail is down with a slight curve upward at the end resembling a sickle. In the Hairless variety, two-thirds of the end of the tail is covered by long, flowing feathering referred to as a plume. The Powderpuff variety's tail is completely covered with hair.
Angulation - Layback of shoulders is 45 degrees to point of shoulder allowing for good reach. Shoulders - Clean and narrow. Elbows - Close to body. Legs - Long, slender and straight. Pasterns - Upright, fine and strong. Dewclaws may be removed. Feet - Hare foot, narrow with elongated toes. Nails are trimmed to moderate length.
Angulation - Stifle moderately angulated. From hock joint to ground perpendicular. Dewclaws may be removed. Feet - Same as forequarters.
The Hairless variety has hair on certain portions of the body: the head (called a crest), the tail (called a plume) and the feet from the toes to the front pasterns and rear hock joints (called socks). The texture of all hair is soft and silky, flowing to any length. Placement of hair is not as important as overall type. Areas that have hair usually taper off slightly. Wherever the body is hairless, the skin is soft and smooth. Head Crest begins at the stop and tapers off between the base of the skull and the back of the neck. Hair on the ears and face is permitted on the Hairless and may be trimmed for neatness in both varieties. Tail Plume is described under Tail. The Powderpuff variety is completely covered with a double soft and silky coat. Close examination reveals long thin guard hairs over the short silky undercoat. The coat is straight, of moderate density and length. Excessively heavy, kinky or curly coat is to be penalized. Grooming is minimal-consisting of presenting a clean and neat appearance.
Any color or combination of colors.
Lively, agile and smooth without being stilted or hackneyed. Comes and goes at a trot moving in a straight line.
