Hello there! I see a slight swelling on the neck under the chin, so I hope that's the lump you're referring to. This swelling could be a number of things - a benign, fatty tumor, a pocket of infection (abscess), or a swollen lymph node or salivary gland. The only way to know for sure would be to visit the vet. You might also try feeling the swelling - if it's painful, it's more likely to be an infection over a fatty mass. At the vet's office, they will give Lillian a full physical exam, and will likely aspirate a small amount of cells from the lump with a small needle to examine under the microscope. This well help determine what the lump is and how to treat it. An abscess will require antibiotics, while a tumor may require removal. Good luck, and I hope that Lillian recovers well!
