You might want to look at some of our products to help with the itching. 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. You might want to try a grain free diet that uses fish or turkey for it's protein source if your dog is not allergic to them. These are considered to be more cooling according to Chinese food therapy.
Defendex shampoo which is nontoxic washes away debris and soothes the skin. Using these products can make a difference in helping to improve the skin.
