If your dog has been diagnosed with a grain intolerance or allergy, you should definitely feed it a grain-free diet. Even if you already know that your dog has a sensitive stomach, grain-free dog food is a good choice.
To ensure that your dog still has a balanced diet and is supplied with carbohydrates, grain-free dog food often contains certain types of fruit and vegetables. These include apples, bananas, peas, potatoes, pumpkin, parsnips and sweet potatoes.
