My dog is drinking water but will not eat. I took her to the vet and they gave her several meds. When I took her home she was fine the first day now she's back to not eating. I can't afford the vet fees they want to charge me over $500 to bring her back for more testing. I have been giving her nutri cal and pedialyte as the vet advised.

So what did the vet say? What were the meds for? What was the additional testing for?
