Please let us know when it is over. I'm sure that he will be fine but be sure to get pain medication. I couldn't tell that Bijou was in pain but I gave it to him at the time intervals that they suggested anyway. I know that one person on this list wasn't sent home with pain medication and she couldn't tell that the dog was in pain but why take a chance. My guess is that with any surgery there would be pain or discomfort.
