15 y/o rescue, yellow lab/whippet mix, female. Have had her for 15 years, no health issues to date, About November had lump on right side of snout, vet had to extract molar and said that the gum had become necrotic. Cut away as much as he could. Antibiotics were working but ran out, lump came back more aggressively. Now is about the size of half a lime, started to let us try an massage it and was getting blood/clots/tissue like material (clear and gummy) out. we have gotten to the point where she will not let us manipulate, still have her on pain meds but starting to question. Last night after manipulation, she has been drooling blood and i have noticed her snot is bloody. We do a warm water/salt rinse after manipulation to try and clear any loose blood. Anyone have experience with this?? Vet says he will not cut out and says no one else will touch it.
