What tests should you take if you want to know exactly what colors your dog carries? I know there are places like this http://www.vetdnacenter.com/canine-dna-coat-color.html where you can test your dog, but how do you know which color tests to try? Aren't there several different ones? B locus d locus and so on. I'm sure you don't have to test for each one OR do you?
