Rice with the bran layer left on, which keeps more fiber, B vitamins and minerals than white rice. It is well digested by most dogs and is a common carbohydrate in sensitive-stomach foods. It digests more slowly than white rice and keeps blood sugar steadier, so it turns up in weight-control foods too. For most dogs and cats it is an unremarkable energy source.

A staple of grain-free recipes, supplying starch, fiber and plant protein. Peas were common in the diets examined in a federal investigation into heart disease in dogs; the investigation did not establish a cause and no ingredient was banned. Pea protein high on a list can inflate the protein number with a plant source. Pea allergy is rare. Not a problem, but worth noticing when it appears in several forms in one recipe.

A vegetable that contributes a little fiber and beta-carotene and a lot of label appeal. In dry food it is usually present in small amounts well down the list. It is not an allergen of concern and not a meaningful protein or calorie source. Fine to see; not a reason to choose one food over another.

A complete, highly digestible protein, which is why formulators like it. It is also a documented allergen in about 4% of dogs with food reactions. Egg allergy does not implicate chicken meat; the proteins are different. Dried egg product is the same thing with the water removed. A good ingredient for most pets and a fine-print one for the allergic few.

A plant oil with the source unspecified, usually soybean, canola or a blend. It supplies the omega-6 fat linoleic acid, which dogs and cats need for skin and coat. The unnamed source means it can change between batches, which matters little nutritionally since the common vegetable oils are similar. Its omega-3 is the plant form, which pets convert poorly, so a food relying on it will add fish oil or flaxseed for balance.
