Thanks for using Petco Pet Education Center, formerly Petcoach! It is not possible to diagnose this based on a picture. Possibilities include inflammatory disease, cancer, immune mediated disease, an infection, among other possibilities. I recommend that you have her evaluated by a veterinarian for further assessment and treatment. They may have to take samples from the lesions to try to find out. They Good luck and have a great day!
