Swollen dog nose - side view
This dog was presented for a very swollen nose, appearing just this morning. She was fine the night before, according to her owners. Nothing else out of order.
Due to the 'sudden' nature of the swollen appearance, an allergic reaction was the first suspect.Continue to 2 of 6 below.

The swelling did not go down with allergic reaction medications (Dexamethasone and diphenhydramine).
The next step was to take radiographs of the nose and skull to see if perhaps a tumor or foreign body was in the nasal area causing the swelling. Sometimes tumors "quietly" grow, then erupt with infection.Continue to 3 of 6 below.

Radiograph (x-ray) of the swollen nose - side view
The radiographs showed "something" there - a tumor? Fluid?
The area in question is just in front of the incisor teeth - the medium white area (opacity) just in front of the upper jaw.Continue to 4 of 6 below.

The tissue to the front and sides of the jaw is markedly swollen, with more uniform opacity on the right side.
The next step was to perform a Fine Needle Aspirate to take a look at the cells making up this swollen mass.Continue to 5 of 6 below.

Not what was expected
What happened next, after the needle was inserted to collect a specimen, was the release of a lot of smelly, stinky pus. (Sorry no photo.)
The large mass was an abscess. First on the rule out list was a grass awn, common in the area that this dog lives.Continue to 6 of 6 below.

The likely culprit
However, upon further questioning, it was determined that this dog had a run-in with a porcupine two weeks earlier. The quills were removed at home, but one must have broken off worked its way in and was missed, causing it to form this abscess.
The area was flushed out well, but no quill remnants were found. This one will need monitoring for future problems. Hopefully, the foreign body was small and flushed out in the process.
This photo depicts the colors and size variations of porcupine quills.... The quills are hollow and black tips break off easily. In this dog, finding small black quills on a black nose and muzzle are difficult at best. Especially two weeks after the incident.
After a thorough flushing of the abscess and some antibiotics, this dog was happy and good to go. Hopefully, she will steer clear of those porcupines.
