Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. It is difficult to say for sure what this could be without feeling it myself. I would suspect that this could be a cyst, abscess or mass. I would recommend having this examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction. Please let me know if you have any further questions or concerns and I would be more than happy to help you further.
