The Nekkid Gene

Despite its reputation as a hairless breed, coated examples do exist in the Peruvian Inca Orchid Dog, and they’re an important part of the breed’s genetic makeup. Like the Xolo and and Chinese Crested, PIOs are dominant for hairlessness, so a dog needs only one copy of the gene to be hairless. As fetuses, any of these dogs that is homozygous (a dog that has two copies of the hairless gene) will be re-absorbed into the womb. If you’re wondering about the American Hairless Terrier, this terrific breed is very unusual because it’s the only known example of recessive hairlessness in dogs.
