Gunner our Boston Terrier started having swollen lymph nodes, they are pretty big and hard middle of last year. Our vet told us to watch and wait could just be a cold ect. So a couple months ago I took him in because they were not going down. So they did bloodwork, his sugar was a little high but nothing else was out of the ordinary. She aspirated them and looked at it on a slide, said she saw nothing bad and thought he could have a bacterial infection. So they put him on antibiotics for a few weeks, it did nothing. She told us she wanted us to wait a bit longer and see if they continue to grow and if so do a biopsy and have it sent in to the lab. She seems to think that this is NOT cancer..I dont know what to think at this point. What else could it be? He is acting just as he always does, happy goofy boy. The only lymph nodes affected are the ones under his jaw.
