First of all, I don't see why you're asking members of Toribash on what to do, but alright.
If your dog is still suffering from this blood clot and broken jaw, you need to take him to the vet. He is seriously injured, but he can pull through as long as he has the care of a vetranarian. Don't put it down yourself, that's how you cause traumatic memories for yourself that will bother you for a long time.
TL ; DR see what the vet says. take him immediately, do not wait. he is suffering right now.
