Hey Jean,
I had a dog years ago with a complete cure from very same thing with high dose safflower oil alone. I found this dose on VIN - 3ml/kg, I assume daily. This was before I knew any Chinese Medicine, so I am sure you could do even better. Safflower is high in Omega 6's, so perhaps they are Qi Deficient in some way?
If pulse wiry and deep, and appetite off on abx, she may need her circulation to move toward the epeithelial surfaces and not driven away....
Good luck and see you soon!
