Characteristic and trait of inheritance

Hereditary hairlessness is genetically transferred in an autosomal codominant trait. Hairless dogs possess the causative mutation heterozygously and are therefore able to have hairless as well as normal puppies. Dogs without the mutation are called “Powderpuff” and exhibit normal fur. Distinguishing Powderpuff dogs and hairless dogs is sometimes very hard for Chinese Crested breed, as the parts with the remaining hair can take various shapes. Dogs which are homozygous for the mutation die as embryo during gestation. Please note, that this genetic test is not validated for proving hairlessness in American Hairless Terriers.


Chinese Crested Dog, Mexican Hairless Dog and Peruvian Hairless Dog

Test duration

1-2 weeks after arrival of the sample in the lab


The DNA test is performed out of EDTA blood or buccal swabs. Required swabs can be ordered free of charge. (Buccal swab order-form). If a swab is sent in, possibly the genetic material is not sufficient to run the test. In this case it would be best to send in an EDTA blood sample.

Testing procedure

Please send in your sample together with the lab order genetic. Results will be transmitted optionally via post, fax or email. After completion of the test you will receive a separate invoice. Payment can be made via credit card or bank transfer.
Breeding club discounts apply if a copy of the membership card is sent together with the respective samples. Due to administrative reasons the invoiced price can not be altered subsequently.
