Have you talked to your vet? The solution is to find out WHY she is itching. But a soothing fix would be a depo injection. It is a steroid that would decrease the itching for a period of time.
There are so many allergens out there. You could try a grain free diet. A Raw Diet. It could be fleas or even something environmental. Good luck with finding that. I know that it's hard to see her suffer
