Coat length (long- / short-haired)

Characteristic and trait of inheritance

One of the most obvious morphological differences among dogs of various breeds is the length of their coat. For the majority of registered dog breeds, the breed standard allows only one coat length. However, variable coat lengths are officially allowed in breeds like Collies, Border Collies, Dachshunds and St. Bernards. In other breeds, such as Pembroke Welsh Corgis, the occasional appearance of long-haired dogs (also called “fluffies” in this breed) has been a problem for breeders.

It has been demonstrated in some dog breeds (e.g. Welsh Corgi, Collie, Border Collie, German Shepherd Dog, Miniature long-haired and Smooth Dachshund) that a missense mutation in FGF5 is associated with the coat length differences. Long hair is inherited in an autosomal recessiv trait, therefore dogs that have a short (smooth) coat may carry the long coat-allele.

Please note: We have changed the nomenclature to the international standards.


All breed

Test duration

3-5 days 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.
