i know there are several threads on this, i tried searching them, but couldnt find what i was looking for......... i just groomed toby yesterday and he is MSOTLY silver now, he has black coming in and out sorta like an ugly duckling..... my question is this: Toby appears to have a "saddle" on

the hair around his midsection is still darker (not black, more of a darker grey ..... but it still has silver roots so it will turn silver eventually) has anyone ever heard of this "saddle" thing?
