She is absolutely adorable! You are great people for taking in a challenged pup.
If you have another dog, this will help tremendously. I did take in a blind pup a while back and it was my shep that helped her.
I really cannot help with any other information as the one I had just followed me or Max. The dog was eventually adopted with another canine buddy.
Best of luck to you and the ophthalmologist appointment. Hopefully something can be done.
