Hi Julie, you can order a color DNA kit from VetGen at 1-800-625-0874 Color is so confusing but I do know that black is dominant and since you have a black dog, you need to stay clear of dogs throwing black, unless you are wanting to breed for black but, from talking with you, I don't think you do. I have a black Lab that when bred to our chocolate Lab would always throw all three colors and even amounts of each, 3 chocolate, 3 yellow (one or two always being a fox red) and 3 black. She was always very consistant. When I bred her to Mikko (bbee), she threw the most gorgeous litter of creams with a variety of apricots, caramels, reds. So, go figure. She obviously has a wide variety of color genes in her DNA. I would love to learn more about color. Hope this helps
