Contributed by Pam Seifert: Last year, DDC Veterinary began offering a DNA test to identify a recessive gene that causes excessive coat length among several “short- coated” breeds. We wanted to let you know that DNA testing for "Fluffy coat" is also now available for Norwich and Norfolk Terriers. Long-haired coat length is inherited as an autosomal recessive trait, therefore dogs that are carriers of the long-hair allele will appear to be short haired but will likely pass on the long-hair allele 50% of the time. A Carrier to Carrier mating will likely result in producing long-haired “fluffy” pups in 25% of the offspring. The 3 genotypes for coat length can be identified with DNA testing: 1) N/N Clear (those having 2 copies of the short-hair allele [N] and appear to be short- haired) 2) N/F Carrier (those having 1 copy of the normal short-hair allele [N] and 1 copy of the long-hair allele [F] and appear to be short- haired) 3) F/F Affected (those having 2 copies of the long-hair allele [F] and appear to be long- haired) Canine samples can be collected easily at home using buccal (cheek) swabs provided as part of a free DNA sample collection kit. Canines can be DNA tested at ANY age. - Turnaround on results is 10 business days of receipt of the samples. Results are also emailed the day of completion. For more information or to order a free sample kit breeders can go here... or call us at 1-800-625- 0874 or email us Thank you for your consideration.
