I am sorry for your friend and her dog that they are facing this. A member here, she is not very active anymore because she has a baby, but her girl had the surgery done successfully.
Here is one of her threads:

You can go to her profile and look up more of her threads, and maybe try to private message her.
Best wishes to your friend and her dog.
