I'm going through the same thing right now!! I gave him a bath yesterday because now he has rusty stuff under his chin and in his wrinkles!! But after the bath the hair is flying out when I brush him. And when he gets his pets its all over the place as well. How old is your dog? Mine will be one on June 3 and I was wondering if they loose puppy fur?????? Not to sure but I just switched his dog food from NVI to fromm because of the rusty stuff, not sure if that will do it.
