Have you had your little girl to the vet. With being 7 years old and upper shoulder hair lose it could be adrenal related. Does she have any other symptons, swollen vulva, hair lose on tail ? We,ve had several adrenal ferrets here at the shelter and they are the usual symptons. Good Luck and a big hug to your little fuzzy.
