Mila's signs could be indicating allergies as well as a skin infection. The skin color changes could be due to this being an ongoing/chronic issue. Sometimes an oatmeal based shampoo helps as well as omega3 fatty acid supplements but if your dog has allergies your veterinarian can discuss long-term control plans with you.
