I have been meaning to comment here based on the experience we had few months back. We took our Shih Tzu in because he had lost vision in his left eye. Dr Norman treated our dog and had us give him drops and medication for 2 month and ouir dog regained at least 95% of his vision back, it was due to dry eye. We are so grateful for the kindness and help, they really have improved our dogs life and ours.
