My girl has it on one of her legs, but I chose not to get it done, because of the recovery period. I read that it is long and painful. Does she really need it? Can she walk; is she in pain? My girl walks and runs with a hop, and she doesn't seem to be in any pain.
I hope and pray that it all works out for you and your little one. How nice of you to take her on, and how terrible of the origional owner to just let her go like that.
