i shaved my yorkie baby, because she prefers to be outside running ,rolling around ,playing . shes not completely bald just short hair for now and still has a bow. its growing back very quickly .when i say hot i mean in the 90's here .she doesn't seem to mind the shorter hair ,i still brush her all the time.
