FreshpetVital Beef & Lamb Recipe with Carrots, Brown Rice, Peas & Sweet Potatoes

A red-meat protein, higher in fat and iron than poultry. Fresh or deboned beef is mostly water and ranks higher on the label than its dry contribution; beef meal is the concentrated form. Beef is among the most common food allergens reported in both dogs and cats, probably because it has been fed so widely for so long. Beef by-products such as liver and heart are listed separately.

Organ meat from the named animal, or unnamed when the label just says liver. Liver is one of the most nutrient-dense foods there is, rich in vitamin A, copper, iron and the B group, and most pets love the taste, which is why it is used both as an ingredient and as a flavor coating. For allergies, the species is what matters, and beef liver is beef. Unnamed liver can come from any species and may vary by batch.

A red-meat protein, fattier than chicken and with a strong flavor many dogs prefer. Fresh lamb is weighed wet, so it sits higher on the list than the meal form would. Lamb was once the standard novel protein for allergy diets, and with wider use it now shows up as a reported allergen too, though still less often than beef or chicken.

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.

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 root vegetable used as a carbohydrate source, especially in grain-free foods. It supplies energy, fiber and beta carotene and is well digested by dogs. There is no good evidence it beats rice or oats nutritionally, though it is a reasonable choice for pets that do poorly on grains. Like any starch, a food that lists it high is a starch-heavy food.

A grain used as an easily digested carbohydrate. White rice has had the bran removed; it digests fast and is the classic bland-diet starch. Brewers rice is the small broken fragments left after milling, nutritionally the same as white rice despite its reputation as a cheap filler. Rice bran is the outer layer, mostly fiber and oil. Grain allergy is rare in pets; rice is one of the least reactive grains.

A vegetable used mainly as a source of soluble fiber for stool quality, and for label appeal. Amounts in a complete food are small. Not an allergen of concern and not a meaningful protein or calorie source.

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.

Oil pressed from whole fish, usually menhaden, herring or sardine, added as the source of the omega-3 fats EPA and DHA. Those fats support skin, coat, joints and brain development, and a food that names fish oil is delivering them in the form pets use directly. It goes rancid quickly, so look for a preservative named alongside it, usually mixed tocopherols. The species is rarely stated, which matters only if your pet reacts to fish.
