I'm sorry. I had a Great Pyrenees that had a ear hematoma in both ears. Not at the same time though. I think he had a chronic yeast infection in his ears that caused him to shake his head a lot which in turn caused the hematoma's. Your pup will feel much better once it's done and over with. It's just one of those things of being a pet owner.
Eta: with my Pyrenees, he had many stitches in his ear after the surgery but the healed up well. After some time, his fur grew back and you couldn't tell it had been done. Plus the vet told me that once they get a ear hematoma, they won't ever get one again.
