my chia is shedding hair from the top of her head. i haven't seen any bald spot as of yet, but the top of her head used to be black with lighter brown around the face and near the ears, on her breast and legs. i thought at first she was losing hair cause i don't use as much shampoo on her head so that it doesn't get in her eyes or ears, but now i don't know. what could cause this??
