Open FarmNew Zealand Venison Dog Food with Ancient Grains

A whole grain used as a carbohydrate and fiber source. Oats are well digested, higher in protein than rice, and contain beta-glucan, a soluble fiber linked to steadier blood sugar. They are a common choice in sensitive-stomach and weight-control foods. Oat fiber is the hull, which is mostly insoluble fiber; oat flour and oatmeal are the whole grain milled. Grain allergy is rare in pets.

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.
