You might want to look at two of our products, Derma-IonX and Defendex shampoo to help heal the skin. Derma-IonX which is an oral homeopathic product stimulates the enzyme systems in the body which reduces itching and inflammation , promotes healing of the skin and helps with assimilation of nutritional components in diet and supplements. The supplements I use along with it include Canine probiotics, vitamin C, MSM, and Omega 3,6,9. Together with Derma-IonX it produces a synergistic effect for a faster response. I would also suggest that you give your dog only filtered water for drinking and bathing if your water contains chlorine or fluoride. For the dietary modifications you might want to try feeding a fish or turkey based diet diet for a while since in Chinese food therapy these are considered to be more cooling than chicken or lamb. Only try these if your dog is not allergic to them. It is good that you have gone grain free.
Defendex shampoo which is nontoxic washes away debris and soothes the skin. Using these products is a simple and effective way of helping resolve a difficult condition.
