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 digestive enzymes, probiotics, and fish oil. Together with Derma-IonX it produces a synergistic effect for a faster response. It can also be used topically if there are troublesome spots on the skin. 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 was designed to fight against fleas and mites also washes away debris and soothes the skin. Using both products is a simple and effective way of helping resolve a difficult condition. After bathing you could apply liquid Iodine to the area. I use the kind that is made for humans for oral consumption because your dog will probably try to lick it. Please feel free to contact us again if you have any other questions. I can give you more suggestions if necessary.
