I will be thinking of Oscar today. This is common practice to do the baby teeth with the neuter, that way they only have to be put under once. He might be a little soar for a day or two, I would just soften his hard food a little if he doesn't seem to want to eat. But that should pass within a few days. Are his adult teeth in behind his baby teeth? If so it shouldn't take him too long to go back to hard. Hugs to Oscar.
