It is a good antibiotic and spray. It should help the immediate problem. However, in order to repair the internal environment that allowed this to occur in the first place I would give Derma-IonX to help stimulate the immune system. Derma-IonX which is an oral homeopathic product also 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, vitamin C, MSM, and fish oil. 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. For the dietary modifications you might want to try a grain free diet for a while. If your dog is not allergic to either of these I would try fish or turkey as the protein source since these are considered to be more cooling than chicken or lamb.
Defendex shampoo which was designed to fight against fleas and mites also washes away debris and soothes the skin. I like to use it on my pets even though they do not have any skin issues just because it is nontoxic and a nice shampoo. Make sure to use only a small amount because it is very concentrated.
