About the breed
The Chinese Crested is a small but surprisingly lively breed that actually hides two distinct looks within the same breed - and even within the same litter: a hairless variety with smooth skin, and a coated variety called the Powderpuff. Both come from the same parents and the same genetic background, differing by only a single gene. Dogs weigh between 3 and 6 kg and stand 23 to 33 cm at the shoulder, making this one of the few breeds where an owner effectively gets two breeds in one. Despite its exotic looks, this is a gentle, emotionally attached companion that thrives on constant closeness with its people.
An origin wrapped in mystery
The name suggests a Chinese origin, but the breed's history is actually far more complicated. Canine and genetic research suggests hairlessness in dogs likely first appeared elsewhere - some sources point to Africa, others to Mexico - from where, carried aboard Chinese trading ships that used hairless dogs as ratters on deck, it spread to port cities around the world. Chinese traders were therefore more carriers than original developers of the trait, yet the name stuck. The breed took its modern form in the 19th and 20th centuries through systematic breeding in the United States and Europe, and was officially recognized by the American Kennel Club in 1991.
The genetics of hairlessness: two breeds in one litter
Hairlessness in this breed is not simply a lack of coat - it results from a precisely described mutation in the FOXI3 gene, which governs the development of skin, hair, and teeth. It is a semi-dominant mutation: dogs with one copy of the mutated gene are hairless, those without it are fully coated Powderpuffs, and embryos that would inherit the mutated gene from both parents fail to develop to term. This means every hairless dog of this breed is necessarily heterozygous, and Powderpuff puppies are born in the very same litters as their hairless siblings. The mechanism was described in a 2008 study published in Science, and works in a manner strikingly similar to the lethal effect of the doubled tailless gene in Manx cats.
Skin care for the hairless variety
Bare skin is the breed's signature look, but it also demands real attention. Without fur, it is more exposed to the sun, so dog-safe, high-SPF sunscreen is recommended for daytime walks, along with protective clothing in summer. The skin is prone to dryness, pimples, and blackheads - not unlike teenage acne - so owners regularly check the skin and use gentle, dog-formulated moisturizers when needed. Bathing too often dries the skin out, while bathing too rarely lets oil and dirt build up, so striking a balance matters. In winter, bare skin chills quickly, which is why many owners dress their dogs in sweaters during colder months.
Teeth: another consequence of the same gene
The same gene responsible for hairlessness also affects tooth development, so hairless individuals of this breed often have incomplete dentition - missing, misshapen, or pointed ('vampire') canines and molars. Powderpuffs, who lack the mutation, typically have a complete, normally developed set of teeth. Incomplete dentition in the hairless variety is not a sign of poor care but an expected genetic consequence, though it still calls for regular veterinary monitoring, since unevenly spaced teeth can accelerate tartar buildup.
Temperament and everyday life
The Chinese Crested is affectionate, playful, and deeply attached to its people, often to the point of struggling with prolonged solitude. It is an attentive companion that loves to curl up in a lap, yet is also surprisingly active and a curious explorer of the home. It is friendly toward familiar people but can be initially reserved with strangers, making early, consistent socialization essential. Given its delicate build, the breed suits calmer households and older children who know how to handle a small dog gently.
Health risks
As with most small breeds, patellar luxation - a slipping kneecap - is common in the Chinese Crested, showing up as a skipping gait and, in severe cases, requiring surgical correction. The breed is also prone to progressive retinal atrophy (PRA), an inherited eye disease that gradually leads to blindness and for which genetic testing is available. Responsible breeders test dogs for PRA before mating and regularly check eyes and knees, substantially lowering the risk for offspring.
World's Ugliest Dog
The hairless variety's unusual looks have brought the breed some unexpected fame: Chinese Cresteds have repeatedly won the well-known American 'World's Ugliest Dog' contest held in Petaluma, California - among them Rascal in 2002, Sam three years running (2003-2005), and Elwood in 2007. The contest actually has a good-natured purpose: it promotes dog adoption and reminds people that looks matter far less than character, and character is where this breed truly shines.
Temperament
Affectionate, playful, and deeply attached to people; loves staying close to family and struggles with long solitude. Friendly toward familiar people, can be reserved with strangers without early socialization. Lively, curious, and surprisingly active despite its delicate build; the Powderpuff variety is often somewhat calmer than the hairless one.
Suitable for
People who want a small, deeply attached dog, spend most of the day at home, and are ready for the hairless variety's special skin care or the Powderpuff's more frequent brushing.
Living environment
Adapts very well to apartment and city living since it needs no large yard, though it appreciates a warm, draft-free space given its sensitivity to cold.
Grooming
The hairless variety needs regular skin moisturizing, protection from sun and cold, and acne prevention, while the Powderpuff needs frequent brushing to avoid matting. Both varieties need regular dental care due to common tooth irregularities, plus moderate daily exercise.
Pros & cons
Advantages
deeply devoted to family, well suited to apartment living, hairless variety sheds no hair around the house
Things to consider
