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. Defendex shampoo which 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. You will also need to treat your house to get rid of the fleas and might need to use something else to break the cycle. Your veterinarian probably has recommended some products that are most effective in your area.
