I would suggest a vet visit for Andie. He could have an abscess, enlarged lymph node, tumor, cyst or swollen salivary gland. But there is no way to know without an exam. After a physical exam the vet may aspirate the mass to see what is in the mass and that may be enough to diagnose it. Thanks for using Petco Pet Education Center, formerly Petcoach
