HI,Welcome to Just Answer. I'm sorry to hear about this guy's situation. How long has he been frothing? Is he still bright and alert? Any vomiting?
About 3 days. No vomitting. Seems to be alert but slow. Also has a droop to the right side of his mouth, stroke? & his tongue is curled up.
Ok. That swelling and the drooling have me worried with it being persistent for that period of time. There could be some very significant dental disease there - a tooth root infection. There could be a growth / cancer there that is altering that tissue. These are my top two rule outs. The dark black foam could be actual blood from either of these two getting into the oral cavity. I would honestly say that my best recommendation is to get him to your vet as soon as possible for them to do a thorough oral evaluation to see what that reveals. Is this something that requires a dental or other form of treatment to take care of?
