Your dog has a serious condition. I would go exactly by what the examining veterinarian advises.
Prescription/therapeutic diet and all. Nothing else, for now. She will eat when she is hungry enough. Offer meals at the same time every day. Pick up and store in the fridg till the next mealtime if not consumed within 15 minutes. I would not be concerned as long as she is drinking water, if she goes 72 hours without eating solid food call the vet and see what he suggests.
