Dear Vanessa:
Assuming the dog doesn't have hot spots, mange sometimes the skin has a fungus condition, which is helped with either soaking with a white distilled vinegar or a more effective remedy a 5% solution of ammonium chloride, for a couple of minutes then rinsed with plain water.
In the long run this skin problem might be helped by adding 1 teaspoon of baking soda in a one liter drinking water as the baking soda helps the digestive process, especially proteins.
