Sorry to hear about your pup. Hope she gets well quick.
My daughter had to have our current dog, a 9yo Shih Tzu (got him as a pup). Two weeks ago we found out the dog is blind. It happened within 24 hrs. Now it seems he is loosing his hearing as well. We don't know what to do. The vet said he will adapt but he is not the same dog. All he does is sleep.
I was never a fan of small dogs. As a kid we had large dogs. This little guy was pretty cool though. He would retrieve anything you threw to him and catch articles out of the air. Very high strung. I miss the old pooch.
