Lifespan
The lifespan of a Chinese Crested Dog can be quite impressive. Many Cresteds live to see 15 years or more.
Common Disorders
While the Chinese Crested dog is not affected by many of the congenital diseases found in many Toy Breeds, they are still prone to a number of conditions. 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.
Conversely, most dogs of the Puff variety have few, if any, dental defects.
Eyes are a concern within the breed, being susceptible to at least two forms of progressive retinal atrophy (PRA) which can eventually lead to blindness. Breeders and owners of Chinese Cresteds should have regular eye exams by veterinary ophthalmologists.
As with all other Toy Breeds, the Cresteds can be prone to patellar luxation. This inheritable condition is caused by shallow knee joints 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.
