You might want to look at two of our products, Derma-IonX and Defendex shampoo to help heal the skin. Derma-Ion 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.
For the dietary modifications you might want to try cooling protein sources such as turkey or fish if your dog is not allergic to them. I would try to avoid venison, lamb, and chicken which are considered to be warming in Chinese food therapy. I would also suggest that you give your dog only filtered water for drinking and bathing if your water contains chlorine or fluoride.
Defendex shampoo is nontoxic, can wash away debris, and soothe the skin. Using both products is a simple and effective way of helping resolve a difficult condition.
