My dog has a swollen throat. What could be causing the neck swelling?

Updated On September 23rd, 2025

Pet's info: Dog | Bullmastiff | Male | neutered | 6 years and 7 months old

My dog has a swollen throat area. It feels more like a swelling than a lump (does not move around when touched, disappears when lying on back as shown in photo). Does not appear painful he is letting me touch it and is pretty much his usual self with regards to energy, eating and drinking ECT. Will be arranging an appointment with his own vet later today but wanted to prepare myself for possibilities.

It is hard to tell from the photo exactly but I am worried about the location of the lump. Dogs have lymph nodes in that area than can become enlarged with lymphoma :( I'm not trying to scare you but that is one possibility. Of course there are other things that it could be: reactive lymph node (not cancer but just inflamed), fatty tumor (benign), cyst, abscess. Your vet will certainly be able to give you a better idea after an exam but be prepared that some testing may be needed. Namely, a fine needle aspirate of the lump and some bloodwork. That will probably be the start. I hope this helps. Best wishes to you and Marv. I hope it is something easy.
