2.Fiber Enriched Oatmeal
If your dog is having difficulty with bowel movements, fiber-rich oatmeal is a healthy way to solve that problem. Shih Tzus generally like the taste of oatmeal, as it similar to the sweetness of milk. When preparing oatmeal for your dog, you can use hot water to make it. Avoid milk to prevent stomach upset. Don't add sugar or any other spices, as these could lead to stomach irritation. Make sure the oatmeal has cooled before serving to your pooch.
