To say it is Lymphoma it would have to be one of her lymph nodes. Typically when it is lymphoma more then one lymph node will be enlarged. If the lymph node is what is getting larger it is not always lymphoma. It can be from an infection draining, it can be viral or it can even be a tick borne disease causing the increase in the size. I recommend having a veterinarian evaluate Jamber and have them see if it is a lymph node and if so typically an aspirate is recommended and a tick panel to rule out lymphoma and tick borne diseases. If they do find lymphoma I would recommend at least a consult with a veterinary oncologist. They will be able to give you the most up to date information on different Chemotherapy options and see if this is the best option for Jamber and your family. If this is is something as a family you decided not to pursue then there is prednisone which they can put Jamber on. Thank you for using Petco Pet Education Center, formerly Petcoach.
