Hi thanks for your question. It is hard to say exactly what the mass could be without examining Cookie and taking a sample of the mass first. This should be done at your local veterinarian's office to determine if it is something of concern or not and if it needs to be removed. I hope this helps and I wish you and Cookie the best!
