Phoebe is 20 weeks old and is turning silver where heir topnot is. I was told the sire's parents and grandparents have this same trait but it looks as though it may eventually go further than just the top of her head. She also looks scruffy and matts pretty easily, close to the skin. Will be nice when that stops happening. Love the dark, puppy colors but combing the coat with matts isn't fun. Guess we'll hang in there together. They are like little mood rings...you never know what color they might end up being
