I would call the neuro office and tell them your predicament! Like Graciesmom said maybe they can recommend a vet. We had similar troubles and had to switch to several different vets to get a referral. So glad I did! I ended up getting apologies from one of the GP vets. I've always told the vets "It will make me feel better to see a specialist so I know what I'm dealing with". Any vet who does not care what the owner thinks should not be in the profession IMO. After all they are our furry children we are trusting them to care for! Can you imagine the outrage if a human doctor or even worse a pediatrician had similar excuses!!! It would be all over the media! I don't understand how vets can be like this!
I hope you get this all sorted out. Maybe Nicki would have some advise on who to go see?
