Thank you for submitting your question regarding Charlie. I recomend she sees her veterinarian. The lesion could be an infection or a a mass that has developed. Depending on her exam findings, the veterinarian may perform a procedure known as a fine needle aspirate. A small needle is used to collect a sample of cells and evaluate them under the microscope to diagnose the lesion. This will help to guide treatment. In the meantime, you can try bathing her with a moisturizing shampoo and conditioner such as an oatmeal or fatty acid based formula. I hope this information helps!
