More: Mia is 10 yrs. old & is missing her back leg. We adopted her that way. She was excessively abused by her previous owner. She is self protective & a little timid, understandably. When we adopted Sidney in June, Mia has looked after her like the sweetest of mommies. They are inseparable. It feels like Sidney helped Mia open her heart back up & heal from the mistreatment she received as a small puppy.
