Looking to coat color test a bitch who is definitely a BC (BYC dam to C sire) and wondering if she carries yellow. Can someone help me as to which vetgen test I need to order? TIA

Check them at DDC.

If you are looking to test for just yellow ("e"), through VetGen, you would want this test: ChromaGene - "e" test – yellow/ white-cream-red-apricot
