  • Coat Color Testing

DNA testing for coat-color genotypes is available for several dogs breeds and helps our clients to more accurately predict the colors of future progeny.

  • Coat Length or “Fluffy” Test

DNA testing for varying coat-length genotypes is available for many breeds. Long-haired coat length is inherited as an autosomal recessive trait. We test DNA marker– FGF5:c284G>T.


  • Coat Curl Test

This screen tests for the presence of 1 or 2 copies of “curl,” which is a dominant trait. DDC has validated this DNA test for 20 popular breeds.


  • Coat Furnishings (IC)

Furnishings is best characterized by a long mustache and eyebrow facial hair pattern. Truth DNA performs this test for more than 15 breeds.

  • Myostatin or “Bully” Test for Whippets

This DNA test determines whether a dog has the gene mutation associated with myostatin deficiency. Affected dogs appear overly muscled. This screen is exclusively for Whippets.

  • Natural Bobtail Test

By identifying the genotypes of phenotypically short-tailed dogs, our clients can accurately determine whether the dog is a Natural Bobtail (genetically short-tailed) or has been artificially docked.
