She is a blue dilute but there is nothing "blue" about that pup. Fawn bluies are fawn dogs with a blue nose and mask. Your pup is champagne in color. Champagne is a the dilute blue like your pup but unless your dog have the color blue on it you do not refer to them as blue. I know confusing isn't? It also doesn't help the person who bred your pup obviously knows nothing of the breed or color.....
This dog is a fawn bluie or a blue fawn depending on what registry
Rogue has a blue nose and a blue mask but her overall color is fawn.
Holly has some good pictures of champagne color dogs that she bred, if she sees this she can post up some examples.
