White rice is safe for dogs to eat and is commonly recommended to help soothe sensitive stomachs. According to Modern Dog, white rice is easily digested even by upset stomachs.
For mild stomach upset, a bit of unseasoned chicken, with the bones removed, along with white or brown rice can help give the dog energy while soothing its stomach. If the stomach issues persist, contact a veterinarian. White and brown rice are also common ingredients in commercial dog foods, especially formulas for sensitive stomachs. Brown rice is lower in fat than white rice, so it may be a better choice for a regular dietary supplement.
