Edgard CooperOatmeal with Peanut Butter Biscuit Dog Treats

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 plant oil, low in saturated fat, added as a source of the omega-6 fat linoleic acid with some plant omega-3 as well. It is inexpensive and stable. The plant omega-3 in canola is not converted efficiently to the forms pets use, so it does not replace fish oil. Canola is often genetically modified, which some owners prefer to avoid; there is no evidence that matters for the pet.

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.

The dried cells of yeast, often a by-product of brewing. It is rich in B vitamins, protein and minerals, improves flavor, and contains compounds that may support gut bacteria. Despite a persistent myth, there is no evidence it repels fleas. Yeast is an uncommon allergen in pets. Yeast culture is a slightly different product, a fermented feed that supplies similar nutrients.

A fruit added for fiber, a little natural sweetness and antioxidants. Apple flesh is safe for dogs and cats. The seeds contain a trace of a cyanide-forming compound, which matters for a dog eating whole apples and is far below any concern at the amounts of pomace or dried apple in a food. Apple pomace is what remains after juicing and is mostly fiber. In either form it appears in small amounts and does not change the nutrition of the food in a meaningful way.
