Hi and thank you for posting your question! From the picture, it looks like a skin tag which can grow over time and become larger. Usually these are not anything to worry too much about, although if it starts to become larger, red, swollen, or infected, you may want to have your veterinarian take a closer look. You can always have the mass aspirated and a sample sample taken from it to see if it is anything concerning. That is the only way to really definitively diagnosis any mass. Thank you for using Petco Pet Education Center, formerly Petcoach and I hope this has helped!
