Legumes such as chickpeas, lentils, and peas are a great source of protein and fiber! Legumes replace grains in many dog foods as a binder to ensure the dry dog food retains its shape, and to add protein to the food.
Adding legumes as an additional protein source also helps with sustainability and decreasing stress on the meat-based food supply. Legumes may appear on an ingredient label as whole peas, pea protein, pea fiber or ground as flour or starch.
When selecting a meat-based grain-free dry food for your dog, make sure that a species-specific meat and/or meat meal is the first ingredient(s), followed by the legumes; dogs are omnivores and do eat a wider variety of foods than cats, but they do need the amino acids and nutrients found in animal proteins.
