Canine DNA Testing for Hair Length, Curl, and Furnishings

DDC Veterinary offers DNA testing for varying coat length and texture genotypes among several dog breeds. By identifying the genotypes of the parents, clients can more accurately predict the possible occurrences of these differing phenotypes in future progeny. Breeders can use DNA testing as a tool to more effectively manage mating patterns and make more informed selection decisions.

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.

A detailed DNA report for each canine tested will be mailed within 10 business days of receipt of the samples. A summary of the result will be emailed the day of completion.

The cost for testing (per canine tested) is $58 (US) for the first coat test and $20 for each subsequent DNA test (on the same dog) requested at the time of sample submission. Payment can be submitted with the return samples.

DNA Testing options include:

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

Hair Curl (DNA marker tested – KRT71) The presence of "Curl" is inherited as an autosomal Dominant trait. Therefore, dogs having only 1 copy of the curl allele will appear to have a curly coat, but will likely pass on the non-curl allele 50% of the time.

Furnishings (DNA marker tested – RSPO2) The presence of "Furnishings" is usually observed in "wire-haired" dogs but is best characterized by a longer mustache and eyebrow facial hair pattern. Like Curl this is also inherited as an autosomal Dominant trait. Therefore, dogs having only 1 copy of the furnishings allele will appear to have "furnishings", but will likely pass on the non-furnishings allele 50% of the time.
