It's time to hire a (for real) homeopathic vet (accept no imitations!). I've got a vetted list on this article for you: vitalanimal.com/diagnosis-or-cure/. I hear you: tough to live with, and rarely curable completely with diet and supplements and such. Be patient with the homeopathy, but a good practitioner can move her to cure. Estimate: 6 months to get there.
