Grains are the seeds from wheat, maize, rye, oats, rice and millet and are an excellent source of amino acids, vitamins, minerals, carbohydrates, fibre and fatty acids that are essential for the health of dogs and cats. Not only do they support the health of our pets helping to provide complete and balanced nutrition, they can also be very sustainable. When it is not possible for pet food manufacturers to list individual ingredients, grains such as rice and maize will be listed under the category "Cereals". Grains used in pet foods are an excellent source of energy, helping to provide complete and balance nutrition. During the manufacturing process the outer husks are removed and the grain is finely ground and cooked, to ensure the grains are digestibility. Pet foods may include one or more grains such as rice, wheat, corn, barley, and oats. While grain-free pet foods have become a popular trend, the dietary value of grains is undeniable, except in very few cases where an allergy is diagnosed by a Vet. Adverse reactions to grains are actually very rare.
