Open FarmSmall Breed Dog Food: Ancient Grain for Small Dogs

A poultry protein, similar to chicken in nutrition and usually a little leaner. Fresh or deboned turkey is mostly water and ranks higher on the label than its dry contribution; turkey meal is the concentrated form. Turkey is often used as an alternative for pets that react to chicken, but the two are related birds and some pets react to both, so it is not a guaranteed swap.

A small, oily fish from the Atlantic and Gulf coasts that rarely reaches the human table and is used almost entirely for fish meal and fish oil. It is a high-protein, omega-3-rich ingredient and one of the most common fish in pet food. Menhaden fish meal is the dried, concentrated form. Pets allergic to one fish often react to others, so the name helps less than it does with meats.

A cereal grain used as a slow-digesting carbohydrate. It is high in soluble fiber, especially beta-glucan, and has a lower glycemic effect than rice, which is why it turns up in weight-control and diabetic foods. Pearled barley has had the hull removed, which lowers the fiber somewhat. Barley grass is a different ingredient, a young green shoot used as a vegetable.
