Some dogs may experience an allergic reaction to simethicone, which can range from mild skin irritation to more serious symptoms such as difficulty breathing or swelling of the face.
Additionally, excessive consumption of simethicone may lead to side effects such as nausea, vomiting, and diarrhea. If your dog experiences any of these symptoms after taking simethicone, it is important to contact your veterinarian right away.
It's important to follow the recommended dosage instructions provided by your veterinarian or the product label to minimize the risk of side effects. If you have any concerns about using simethicone for your dog, it's best to consult with your veterinarian before administering it.
