Some nausea and diarrhea can be expected after deworming a pet with intestinal parasites, but it should not cause excessive vomiting or affect their activity level. Make sure that Shiro is still drinking plenty of water. If he is not used to eating yogurt, it can cause diarrhea. I would stick to puppy food (wet puppy food may be more palatable right now).
