Now Available: DNA Testing for “Fluffy” long-hair genotypes among Pembroke Welsh Corgi

From the American Kennel Club Pembroke Welsh Corgi Breed Standard for Coat Length:

DDC Veterinary is now offering a DNA test developed at Michigan State University by Drs. Donna Housley and Patrick Venta with the cooperation of several breeders who donated research samples. 

The purpose of this new test is to accurately identify coat length genotypes. Breeders can use DNA testing as a tool to more effectively manage mating patterns and make better selection decisions.

Commonly referred to as the "DNA Fluffy Test," there are 3 possible genotypes:

1. N/N Clear (those having 2 copies of the normal short-hair allele [N])
2. N/F Carrier (those having 1 copy of the normal short-hair allele [N] and 1 copy of the long-hair mutation [F])
3. F/F Affected “Fluffy” (those having 2 copies of the long-hair mutation [F])

“Fluffy” 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 “fluffy” mutation 50% of the time.

• DNA samples can be collected easily at home using buccal (cheek) swabs provided as part of a free DNA sample collection kit. 

• Dogs can be DNA tested at ANY age.

• The cost for testing is $58 (US) per canine with a $10 discount per test for 5 or more samples submitted at the same time. Payment can be submitted with the return samples.

• A detailed DNA report will be mailed within 10 business days of receipt of the samples.  Results can also be emailed to avoid any potential delays with regular mail service.

• Samples can be mailed to:DDC Veterinary,  One DDC Way, Fairfield, Ohio 45014
