In a last ditch effort the vet and my friend+her fiance have decided to try some medication... no guarentee it will work but the neurologist said he had a yorkie come in with similar symptoms about 3 weeks ago and it worked for him. My friend said she saw some improvement last night and when my friends furture father-in-law checked on her this morning he saw some improvement too!
I'm feeling very optimistic and hoping she makes a full recovery!
