Thanks for using Petco Pet Education Center, formerly Petcoach! I am afraid that while this could be an extra unilateral nipple, it actually is most likely a cutaneous mass. This could be a benign or malignant growth. 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 am really hoping for something benign. Good luck and have a good day!
