So , for example , Dobermans come in black , red , blue , or fawn dilute red , they call it fawn all with tan points . The tan points on a blue dog and a black dog can be identical . The tan points on a red dog and a fawn dog can be exactly the same . If you had a dog with a saddle pattern , like a GSD or a beagle , only the black parts on the saddle or mask would be diluted . The tan would not be . Your dog is a clear sable or fawn with a mask . The only black pigment in his coat would have been that mask , so that mask is all that was diluted to blue . If he had tipping or shading of any kind , like a sable collie or sheltie , then all the black tipping or shading would have been blue . The dilute gene doesn ' t do much to hair that isn ' t black or liver though and can easily go unnoticed . The nose , eye rims , and eye color together will tell though .
