Good Morning and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
Because of Nutmeg's age, this mass is either a benign skin tumor or scar tissue from an injury. It is a good sign that it is not painful and this may resolve on its own. If this does get larger than twice the size, then it is best, XXXXX XXXXX it is not going to harm Nutmeg, to have this removed. Better to be safe since if it grows any larger, it will be even more difficult to remove and may ulcerate and cause bleeding or interfere with function so Nutmeg hits it on things causing it to bleed.
Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please REPLY so I can clarify for you.
Sincerely, XXXXX XXXXX
