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. The breed also suffers from another eye disease called Keratoconjunctivitis sicca or dry eye syndrome (DES).
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 it becoming a problem for the breed.
The lifespan of a Chinese crested dog can be very long. Many live 12 to 14 years or more.

Famous quotes containing the word health:
“No one ever promised me it would be easy and it’s not. But I also get many rewards from seeing my children grow, make strong decisions for themselves, and set out on their own as independent, strong, likeable human beings. And I like who I am becoming, too. Having teenagers has made me more human, more flexible, more humble, more questioning—and, finally it’s given me a better sense of humor!”
—Anonymous Father. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 4 (1978)
“Men’s hearts are cold. They are indifferent. Not all the coal that is dug warms the world. It remains indifferent to the lives of those who risk their life and health down in the blackness of the earth; who crawl through dark, choking crevices with only a bit of lamp on their caps to light their silent way; whose backs are bent with toil, whose very bones ache, whose happiness is sleep, and whose peace is death.”
—Mother Jones (1830–1930)
“The community and family networks which helped sustain earlier generations have become scarcer for growing numbers of young parents. Those who lack links to these traditional sources of support are hard-pressed to find other resources, given the emphasis in our society on providing treatment services, rather than preventive services and support for health maintenance and well-being.”
—Bernice Weissbourd (20th century)
