Hair or what is known as fluff in Pembroke Corgis
About
Hair Length (DNA marker tested – FGF5) Long-haired coat length is inherited as an autosomal recessive trait. Therefore, dogs that are carriers of the long-hair mutation will appear to be normal (short hair) themselves, but will likely pass on the long-hair allele 50% of the time. Breeds we are currently able to test include: Alaskan Malamutes Bullmastiff Chihuahuas Cardigan Welsh Corgis Dachshunds Dalmatians German Shepherd Dogs Labrador Retrievers Mastiffs Norfolk Terrier Norwich Terriers Pembroke Welsh Corgis Rottweilers Schipperke Shiba Inus Weimaraners https://vetdnacenter.com/dna-tests/canine-dna-testing/inherited-traits-testing/ and https://www.pawprintgenetics.com/products/tests/details/172/?breed=41
There was much talk about not using a Fluffy to breed with when we first came in the breed but the fluff is a condition and if you know the genetic make up of your dogs and you have a fluff clear you wont get a fluff in the litter. At Risk X Clear = Carrier. Problem is that the dogs developing DM are mostly fluffs or glamour coated. I know of only one very light coated fluff that we know to be DM clear.
In my opinion the fluff came from trying to get a bigger coat by breeders in the 1950’s and crossing a corgi with a sheltie. If you look at the American standard it says that small eyes and narrow snowt are undesirable features. Well that looks like a sheltie cross. This can also be seen in the old Welsh Corgi League yearly books of the 1950s and 60s.
