From the picture it actually looks more like a deep skin infection to me. This could be bacterial or fungal, or even a hypersensitivity reaction (less likely). I would recommend that she be examined by your veterinarian soon. They may look at a sample under the microscope to help determine what therapies might be most helpful. Best of luck and I hope she improves soon. Thank you for using Pet Coach.
