Nala is a 10 year old female spayed Pit Bull mix that has a chronic history of recurrent, non-seasonal pyoderma. Throughout the years the inflammatory conditions have spread to her ears and eyes (otitis externa and blepharodermatitis). Her skin is accompanied by a strong musty odor always - which is responsive to antibiotics and anti-yeast drugs. She is also prednisone responsive. She was on kibble for most of her life but was changed to a raw unprocessed diet about 6 months ago and her dermatitis improved by about 50%. However her musty, oily coat has persisted as well as a substantial amount of the itch. Her lesions are generally on ventrum and lateral hindlimbs. She was also looking very skinny and malnourished before the transition to raw unprocessed diet, but has put on some much needed weight and looks much better. Her pulse is deep, fast, toneless and is weaker on the left. Her tongue is dry and somewhat pale. She also has history of dry stools.
For her chronic damp heat and secondary yeast/bacterial infections, what formula would be the most helpful? I have been considering Si Miao San and Chu Shi Wei Ling Tang. Would any of these make her yin deficiency worse? Thanks so much!
