My dog is white, but you said it isn't!

Coat color genetics explained

Coat color genetics is very complex. While logged in to your dog's DNA report, click on the "Advanced" tab. Then locate the "Traits report" section and click on "Show descriptions" to learn more about each test. There are two types of pigment in dogs. Eumelanin is found in the coat and is present in the other parts of the dog that need pigment—most notably the eyes (irises) and nose. On the other hand, phaeomelanin doesn't affect the eyes or nose and is only visible in the coat. 

At the E locus, dogs that are ee can be "red" regardless of the other loci (this would be dominant over the A and K). We use the term red, but as you can see in these photos (http://www.doggenetics.co.uk/masks.html), many of the dogs are yellow, cream, or even appear white. This can be controlled by the intensity gene, which is currently poorly mapped. As a result, the genetics are not completely known, so we cannot test for it. There are a few other genes that can control white as well. For example, we are not currently reporting on the albinism or spotting genes which can affect the whiteness in eyes and coat.
