DERMA-IONX has been helpful for a variety of different skin conditions. You can try it along with the other recommended supplements to see if it will allow the skin to heal without the use of antibiotics. DERMA-IONX is an oral homeopathic product which stimulates the enzyme systems in the body that aid the skin and helps with assimilation of nutritional components in diet and supplements. What sets it apart from most homeopathics is that it is in an oligotherapeutic mineral base which has had a charge added to it.
Initially I would give a half dose of DERMA-IONX on the breakfast and supper food. After there are signs of improvement you can give a whole dose once a day. I would also give PROBIOTICS to aid digestion and the immune system. I would also give OMEGA 3,6,9 to reduce inflammation and aid the skin and coat.
The water you give should be filtered if it contains chlorine. Chlorine is not good for the intestinal flora.
Diet can also influence the skin. Sometimes the flavor even makes a difference. Please read the label to check what proteins are in your food. When there are skin problems I usually choose a grain free food. If your dog is warm and seeks cool places then I would choose cooling proteins such as fish or turkey as the protein source according to Chinese food therapy. One of these might help the skin the skin heal more quickly because the skin is usually warmer than usual when there is an infection and it will benefit from cooling. It is interesting that antibiotics are usually very cooling. If your dog is cool and seeks warm places then chicken, lamb, or venison might be better. Beef is neutral. If your dog is allergic to a protein do not use it even if it has the correct thermal properties. Any food changes need to be phased in gradually, starting with a little new food added to the regular food. Please keep us updated so we can help guide you.
