My 6 yr old chihuahua "willy" was sick last week with a large bump under his right eye. I took him to the vet and she said it was probably a tooth abscess. She put him on antibiotics and scheduled him for an abstraction. The antibiotics seem to make him feel better but the bump stayed. After 5 days the bump seemed to rupture on the outside of his face leaving a small bloody spot but apparently didn't drain because the bump is still there although not as big. Is this a tooth abscess or not? The abstraction will be very expensive and I want him to get well but don't want unnecessary surgery or expense.
