The Shar Pei, or Chinese Shar-Pei, is a breed of dog known for its distinctive features of deep wrinkles and a blue-black tongue. The breed comes from China. The name (沙皮, pinyin: shā pí; English name probably derived from British spelling of the Cantonese equivalent, sā pèih) translates to "sand skin" and refers to the texture of its short, rough coat. As puppies, Shar Pei have numerous wrinkles, but as they mature, these wrinkles loosen and spread out as they "grow into their skin". Shar Pei were named in 1978 as one of the world's rarest dog breeds by TIME magazine and the Guinness World Records. It is one of the ancient dog breeds, but the American Kennel Club did not recognize the breed until 1992.[2]
Lineage
Nearly all dog breeds' genetic closeness to the gray wolf is due to admixture.[3] However, several Arctic dog breeds show a genetic closeness with the now-extinct Taymyr wolf of North Asia due to admixture. These breeds are associated with high latitudes - the Siberian husky and Greenland dog that are also associated with arctic human populations, and to a lesser extent the Shar Pei and Finnish spitz. An admixture graph of the Greenland dog indicates a best-fit of 3.5% shared material, however an ancestry proportion ranging between 1.4% and 27.3% is consistent with the data. This indicates admixture between the Taymry wolf population and the ancestral dog population of these 4 high-latitude breeds. This introgression could have provided early dogs living in high latitudes with phenotypic variation beneficial for adaption to a new and challenging environment. It also indicates the ancestry of present-day dog breeds descends from more than one region.[4]
Description
Appearance
Small, triangle ears, and a high-set tail also give the Shar Pei a unique look. For show standard, "the tail is thick and round at the base, tapering to a fine point" (AKC standard February 28, 1998). As puppies, Shar pei are a lot more wrinkly than adults and, although some adults can be wrinklier than their puppy self, an adult pei should have wrinkles mostly on the face, a few on their shoulder and at the base of the tail.
Colors
Their pigmentation resemble the Chow Chow as they've been crossed before, probably giving them the same blue-black tongue. There are over sixteen recognized colors in AKC. The coat must be solid in color, and any Shar-Pei with a "flowered coat" (spotted) or black and tan in coloration (i.e. German Shepherd) is a disqualification. Colors include black, blue, cream, fawn, red-fawn, red, sable, apricot, chocolate, and isabella. The nose may be black or brick (pink with black), with or without a black mask. A Shar-Pei can also have what is called a "dilute" coloration, meaning the nose, nails and anus of the dog are the same color as the coat, (i.e. chocolate coat with chocolate nose, nails and anus). All of these color variations are acceptable and beautiful, but the coat color must be solid and well blended throughout the whole body of the dog.
Coat
Horse-coat (unusual but regaining ground), rough to the touch, extremely prickly and off-standing, soft in one direction and harsh in the other; Brush-coat, with longer hair and a smoother feel; and Bear-coat (rare, and not recognized by the AKC; Bearcoats are due to the addition of other breeds). Examples of the breed were owned by the peasant class, and were used for working dogs and fighting due to their loose skin. Shar pei can be seen in Chinese art throughout history, and are considered to be one of the oldest dog breeds on earth. Western Shar Pei comes in three different coat types: horse, brush, and bear coat. The unusual horse coat is rough to the touch, extremely prickly and off-standing and is closer to the original traditional Shar Pei breed in appearance and coat type than the brush or bear coat. This coat is fairly prickly and can be rough or irritating when petting in the opposite direction of the fur. The horse coat is generally thought to be more active and predisposed to dominant behavior than the brush coat. The brush-coated variety have slightly longer hair and a smoother feel to them. The brush coat is generally considered to be more of a "couch potato" than the horse coat.
This breed sheds normally twice a year[5] (see Moult).
The Chinese Shar-Pei is a unique and intelligent dog most often recognized for its wrinkles. Initially developed as a Chinese farm and hunting and later fighting dog, the breed does well today in obedience, agility, herding and tracking, with skills that would have been needed on the farm. Because the name Shar-Pei means "sand coat", harshness is a distinctive feature in its two accepted coat types, either horse (short) or brush (up to an inch long). Other unique qualities include black mouth pigment, a slightly "hippo-like" head shape, small ears, deep-set eyes and rising top-line.
Any coat longer than one inch at the withers is called a "bear coat" and is not considered breed standard, as it occurs only when both the male and female carry recessive coat genes. This coat length resembles the coat of the Chow Chow and was probably inherited from the chows. The personality of the bear coat is very much like that of a brush coat.
Wrinkles
The traditional Shar Pei that is most popular in China is more faithful to the history of the breed (taller, less wrinkly, flatter mouth and nose, horse coated). As puppies, they have lots of wrinkles and as they get older, they get fewer wrinkles.
Scientists from the Department of Genome Sciences at the University of Washington, Seattle, announced in January 2010 that they had analysed the genetic code of 10 different pedigree dog breeds. In the Shar-pei, they discovered four small differences located in the gene HAS2 which is responsible for making hyaluronic acid synthase 2. That enzyme makes hyaluronic acid, which is one of the key components of the skin. There have been rare cases in which a mutation of the same gene has caused severe wrinkling in humans as well.[6]
Temperament
All Shar-Pei puppies need early socialization with children, strangers, and other animals. Some people may experience a sensitivity to the harshness of the coat of either length. This is a mild, short-lived rash that can develop on the skin that has been in contact with the coat, most commonly on the forearms.
The Shar Pei is often suspicious of strangers, which pertains to their origin as a guard dog. It is a very independent and reserved breed. Nevertheless, the Shar Pei is extremely devoted, loyal and affectionate to its family and is amenable to accepting strangers given time and proper introduction at a young age. If poorly socialized or trained, it can become especially territorial and aggressive. Even friendly and well-socialized individuals will retain the breed's watch dog proclivities (like barking at strangers). It is a largely silent breed, barking only when it is playing or worried. The Shar-Pei were originally bred as palace guards in China. Although Shar-Pei are sometimes stubborn, they are receptive to fair, compassionate training. With repetition and a clear reward system, training is not very difficult, however they do not respond well to negative and cruel treatment. Overall, the Shar Pei can be a dog that is loyal and loving to its family while being very protective. Shar-Pei do not like to be alone, preferring to be close to their humans, often lying nearby in the same room. [citation needed]
Health
Because of its popularity after being introduced to North America in the 1970s, the breed suffered much inexperienced or rushed breeding.[citation needed] This resulted in not only a dramatically different look for the Shar-Pei (as its most distinctive features, including its wrinkles and rounded snout, were greatly exaggerated), but also a large number of health problems.[citation needed] The American breed club states that few Shar Peis make it to age 10 and has a longevity program that records dogs that live 10 years or more.[7]
Allergy-induced skin infections can be a problem in this breed.[citation needed]
Familial Shar Pei fever (FSF) is a serious congenital disease that causes short fevers lasting from 24 hours, sometimes up to three days and usually accompanied by accumulation of fluid around the ankles (called Swollen Hock Syndrome).[citation needed] Amyloidosis, a long-term condition, is most likely related to FSF, caused by unprocessed amyloid proteins depositing in the organs, most often in the kidneys or liver, leading eventually to renal failure.[citation needed] The disease is associated with the western type and it is estimated that 23% are affected.[8] The Australian breed standard was changed in 2009 to discourage breeding for heavy wrinkling.[9]
A common problem is a painful eye condition, entropion, in which the eyelashes curl inward, irritating the eye. Untreated, it can cause blindness. This condition can be fixed by surgery ("tacking" the eyelids up so they will not roll onto the eyeball for puppies or surgically removing extra skin in adolescent and older Shar Pei).[10] In Australia, more than 8 in 10 Shar Peis require surgery to correct eye problems.[11]
The Shar-Pei is also prone to chronic yeast infections in its ears. This is due to tight inner ear structure with a wrinkled appearance, making cleaning very difficult; exacerbated by the tight "flap" that the ear creates over the canal, promoting a moist environment.[citation needed]
Vitamin B-12 deficiency is a common problem in the Shar Pei and is suspected to be hereditary.[1][2]
History
The Shar Pei has been identified as a basal breed that predates the emergence of the modern breeds in the 19th Century.
The Shar Pei breed comes from the Guangdong province of China. The original Shar-Pei from China looked very different from the breed now popular in the West. People in southern China, Hong Kong, and Macau differentiate the Western type and the original type by calling them respectively 'meat-mouth' and 'bone-mouth' Shar-Pei.
The Shar Pei's loose skin and extremely prickly coat were originally developed to help the dogs fend off wild boar, as they were used to hunt. Later, the breed was used for dog fighting; these enhanced traits made the Shar Pei difficult for its opponent to grab and hold on to, and so that if it did manage to hold on, the Shar Pei would still have room to maneuver and bite back; when grabbed by any loose wrinkle, a Shar Pei can actually twist in their skin and face in their opponent's direction. In fighting, they would twist in their skin to bite the assailant back.
During the Communist Revolution, when the Shar Pei population dwindled dramatically,[12] dogs were rescued by a Hong Kong businessman named Matgo Law, who in 1973 appealed to Americans through a dog magazine to save the breed. Around 200 Shar Peis were smuggled into America. The current American Shar Pei population stems mainly from these original 200.
