Those spots on Ivory could be several things including allergies, skin mites, flea bites, ringworm (which humans can get) or a bacterial infection. You can try adding in an omega 3 fatty acid supplement for dogs, this can help improve the skin health. You may also try changing her diet to something like Royal Canin or Nutro as they are aimed at skin health. You can wash the lesions with soap once a day and rinse well (don't wash her whole body, just those spots). Protect the areas from licking or scratching. If they don't start looking better within about a week or if they get worse, have her examined by the veterinarian who may prescribe medications. Best of luck and please feel free to post any additional questions.
