Thanks for using Petco Pet Education Center, formerly Petcoach! It is possible to know without being able to examine her. However, this could be a benign or malignant growth or even a normal pigmentation change. There is no way of knowing what it is just based on its appearance. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!
