[Ellie May]

I would hope the vet isn't getting upset with you giving your input.
I give my input all the time to Ellie's vet and instead of being frustrated about it, she thinks we are great clients probably because we put the time and effort into taking care of Ellie. If you aren't satisfied or you don't think this vet is a great fit, why not switch?

Have you looked into CANNED L/D?
It isn't a great food but it isn't horrible either.
Natural Balance Vegetarian might be acceptable.
I like homecooking best but you would probably need to talk to a nutritionist and it does take some time to do.

Chicken may be okay for some liver compromised dogs but if she is having neurological symptoms, I would not give any extra protein.
