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. == In popular culture == At first look, the Hairless and Powderpuff varieties of Chinese Crested Dogs appear to be two different breeds, but hairlessness is an incomplete dominant trait within a single breed. In addition to being an incomplete dominant gene, the 'hairless' gene has a prenatal lethal effect when homozygous. Zygotes affected with double hairless genes (1 in 4) never develop into puppies, and are reabsorbed in the womb. All Hairless Chinese Crested Dogs are therefore heterozygous.
