Chinese Crested Breed Standard

General Appearance
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.

Head
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.

Forequarters

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.

Hindquarters

Angulation - Stifle moderately angulated. From hock joint to ground perpendicular. Dewclaws may be removed. Feet - Same as forequarters.

Coat
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.

Color
Any color or combination of colors.

Gait
Lively, agile and smooth without being stilted or hackneyed. Comes and goes at a trot moving in a straight line.

Temperament
Gay and alert.

Chinese Crested small breed Dog

 

The Chinese Crested Dog is a smaller (10–13 lbs) hairless breed of dog. Like most hairless dog breeds, the Chinese Crested comes in two varieties, both with and without fur, which are born in the same litter: the Hairless and the Powderpuff.

Description

At first glance, the "Hairless" and "Powderpuff" varieties of Chinese Crested Dogs appear to be two different breeds, but hairlessness is an incomplete dominant trait within a single breed. The Hairless has soft, humanlike skin, as well as tufts of fur on its paws ("socks") and tail ("plume") and long, flowing hair on its head ("crest"). In addition to being an incomplete dominant gene, the "hairless" gene has a prenatal lethal effect when homozygous. Zygotes affected with double hairless genes (1 in 4) never develop into puppies, and are reabsorbed in the womb. All hairless Cresteds are therefore heterozygous.

The Hairless variety can vary in amount of body hair. Fur on the muzzle, known as a beard, is not uncommon. A true Hairless often does not have as much furnishings (hair on the head, tail, and paws). The difference between a very hairy Hairless and a Powderpuff is that the Hairless has a single coat with hairless parts on the body, while the Powderpuff has a thick double coat. The skin of the Hairless comes in a variety of colors, ranging from a pale flesh to black. Hairless Cresteds often lack a full set of premolar teeth, but this is not considered a fault.
The look of the Powderpuff varies according to how it is groomed. When its fur is completely grown out on its face, it strongly resembles a terrier; however, the Powderpuff is usually shaved around the snout as a standard cut.
The amount of body hair on the hairless variety varies quite extensively, from the true hairless which has very little or no body hair and furnishings, to what is called a 'hairy hairless', which if left ungroomed often grows a near-full coat of hair. These hairy hairless are not a mix between powderpuffs and hairless Chinese Cresteds, but are merely a result of a weaker expression of the variable Hairless gene. The mutation responsible for the hairless trait was identified in 2008.
One famous Chinese Crested dog was the hairless purebred named Sam, was the winner of the World's Ugliest Dog Contest from 2003 to 2005. He died before he could compete in 2006. Other Chinese Cresteds have finished high in the event as well.



Care

Both varieties require certain amounts of grooming. The Puffs have a very soft and fine double coat that requires frequent brushing to avoid matting. Although a Puff's coat does not continuously grow like that of some other breeds, it can grow to be quite long at full length. This breed has little to no shedding.
Maintenance of the Hairless variety's skin is similar to maintaining human skin—and as such it can be susceptible to acne, dryness, and sunburn. Hypoallergenic or oil-free moisturizing cream can keep the skin from becoming too dry when applied every other day or after bathing. Burning can occur in regions that lend themselves to strong UV-rays, especially in lighter-skinned dogs. Many owners apply baby sunscreen to their pets before spending time in strong sun. Some Cresteds have skin allergies to Lanolin, so be cautious when using any products that contain it.
Unless the dog is a "True" Hairless (one with virtually no hair growth on non-extremities), trimming and/or shaving is often performed to remove stubble growth.
The Chinese Crested is further distinguished by its hare foot, (having more elongated toes) as opposed to the cat foot common to most other dogs. Because of this the quicks of Cresteds run deeper into their nails, so care must be taken not to trim the nails too short to avoid pain and bleeding.

Health

The crested is not affected by many of the congenital diseases found in toy breeds. They are, however, prone to some of the conditions below.

Cresteds have what is called a "primitive mouth". This means that most of their teeth are pointy like their canines. Hairless varieties of the Cresteds can be prone to poor dentition. Poor dentition may include missing or crowded teeth and teeth prone to decay when not properly cared for. Most dogs of the Puff variety have few, if any, dental defects.
Eyes are a concern within the breed, having at least two forms of progressive retinal atrophy (PRA) which can eventually lead to blindness. For one of these forms of PRA, there exists a genetic test, prcd-PRA. Since this test can only reveal the existence of affected or carrier status of this one form of PRA, breeders and owners of the breed should still have regular eye exams by veterinary ophthalmologists.
Along with Kerry Blue Terriers, Cresteds can develop canine multiple system degeneration (CMSD) also called progressive neuronal abiotrophy (PNA) in Kerry Blue Terriers. This is a progressive movement disorder that begins with cerebellar ataxia between 10 and 14 weeks of age. After 6 months of age, affected dogs develop difficulty initiating movements and fall frequently. The gene responsible has been mapped to canine chromosome 1.
As with all other toy breeds, the Cresteds can be prone to patellar luxation. This inheritable condition is caused by shallow knee joints (stifles) and results in kneecaps that pop out of place. Its onset is often at a young age, and can cause temporary to permanent lameness based on the severity. Breeders should have their stock certified free of patellar luxation. Many countries' kennel clubs maintain a centralised registry for health results.
Allergy and autoimmune diseases have been observed in the breed. The severity of these ailments, which can lead to the premature death of the dog, means this is something breeders need to take seriously in order to avoid this becoming a problem for the breed.
The lifespan of a Chinese Crested Dog can be quite impressive. Many well-cared-for Cresteds live to see 15 years or more.

History

Although hairless dogs have been found in many places in the world, it is unlikely that the origins of the modern Chinese Crested are in China. In the 1920s, Debora Wood created the "Crest Haven" kennel and began to purposefully breed and record the lineages of her Chinese Crested dogs. Crest Haven dogs were the true foundation of every Chinese Crested alive today. Ms. Wood also founded the American Hairless Dog Club in 1959, which was eventually incorporated into the American Chinese Crested Club (ACCC) in 1978. The ACCC became the U.S. parent club for the breed when the Chinese Crested was recognized by the American Kennel Club thirteen years later, in 1991.
The Chinese Crested was officially recognised by the Fédération Cynologique Internationale in 1987, by The Kennel Club (UK) in 1981, by the American Kennel Club in 1991, and by the Australian National Kennel Council in 1995.
The Chinese Crested breed, either in purebred form or as a hybrid with chihuahua, has won eight World's Ugliest Dog Contests.

Breeding

The Hairless allele (the wild type) is a dominant (and homozygous prenatal lethal) trait, while the Powderpuff allele acts as a simple recessive trait in its presence. Zygotes that receive two copies of the Hairless allele will never develop into puppies. Thus all Chinese Cresteds carry at least one copy of the Powderpuff allele.
The Powderpuff trait cannot be bred out because it is carried by all Chinese Cresteds (even the hairless ones). All Hairless Chinese Crested have the ability to produce Powderpuff puppies, even when they are bred to another Hairless. On the other hand, Powderpuffs bred to another Powderpuff can never produce hairless puppies, since they do not carry the Hairless gene.
