Hi there and thank you for using pet coach to address your concern. From the pictures that you have provided the skin masses that you have noticed look very similar to a benign skin tumor known as a sebaceous adenoma. I call these old dog warts when using layman's terms. These are typically benign tumors of the skin which occur with older aged animals. If you are at all concerned about these then I would suggest having your veterinarian examine them and make a determination on what exactly they are. Otherwise, I would continue to monitor them for changes such as an increase in size then I would suggest having your veterinarian examine them and make a determination on what exactly they are. Otherwise, I would continue to monitor them for changes such as an increase in size or if they begin to discharge. I hope this helps! Please do not hesitate to contact me if you have any further questions or concerns. I am also available via phone or text based consultation if needed.
