Go to Walmart or any store in the pet care department and look for medication for it's called Hot Spots or there is similar ones. Apply it on the areas as it will take away some of the irratation so they can heal. It worked on my cat or you could try aveeno oatmeal lotion or make your own with a little oatmeal and water. It's messy but it will work because oatmeal has healing properties to it. You could also use aloe cream or a leaf from an aloe plant. A little aloe goes a long way!
