Hello, Smurf's skin tag may not be much to be worried about since it has been there for over a year. However it is not your typical skin mass in terms or color and appearance and some of those dark pigmented skin masses can be malignant. The only way to really know though is by removing it. I would consult with your veterinarian about removing the mass and submitting it for biopsy so that your can know for sure if it is benign or malignant. The mass is small so surgery shouldn't be too extensive, but they may require pre-surgical bloodwork and x-rays. Hope this helps and best of luck.

    I would suggest a vet visit for Smurf. It may be benign, but any growth that has different coloration that surrounding skin or changes in size could potentially be cancer. The vet can assess and give you options if cytology will help diagnose it or biopsy and what the best course of treatment is.
