Chinese Crested health: what owners should know

Beyond the dental problems linked to the hairless gene, the Chinese Crested is known for inherited eye conditions, particularly primary lens luxation and a form of progressive retinal atrophy. Kneecap problems, a hip condition called Legg-Calve-Perthes disease and skin allergies are also seen. The hairless variety is prone to sunburn, blackheads and sensitive skin.

DNA tests exist for primary lens luxation and the breed's main form of progressive retinal atrophy, and good breeders use them alongside yearly eye examinations and kneecap checks. Ask for the certificates. Contact a vet quickly if an eye suddenly becomes red, cloudy or painful, if your dog holds a back leg up while walking, or if skin lesions blister, bleed or spread.
