Health ExtensionGrain Free Buffalo & Whitefish Recipe Dry Dog Food

A lean, mild fish, often cod, haddock, pollock or a mix, used as a protein source. Whitefish is lower in fat and omega-3 than salmon or herring and is chosen for its gentle flavor and digestibility. The term covers several species, so it is less specific than salmon or herring for an owner tracking a fish allergy. Whitefish meal is the concentrated, dried form.

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 red-meat protein, nutritionally similar to beef and fattier than poultry. The meal form is the concentrated one; fresh pork is mostly water. Pork is less commonly reported as a pet allergen than beef, chicken or lamb, which has made it a useful alternative protein. Pork liver, plasma and fat appear under their own names.

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 legume used as a carbohydrate and plant protein, common in grain-free foods. Chickpeas supply fiber, folate and protein that lifts the number on the bag without adding meat. Legume-heavy grain-free foods were part of the FDA's 2018 to 2022 look at diet-associated heart disease in dogs, which did not establish a cause. A food that lists chickpeas or peas in the first few ingredients is leaning on plant protein.

A small legume used for carbohydrate, fiber and plant protein in many grain-free foods. Lentils supply folate and iron, and like peas and chickpeas they add protein without adding meat. Lentils were among the legumes in the FDA's heart-disease review, which did not establish a cause. A food with lentils high on the list is a plant-protein-forward recipe.

Oil pressed from salmon, added for the omega-3 fats EPA and DHA that support skin, coat and joints. It does the same job as generic fish oil but names its source, which helps if your pet reacts to other fish. Like all fish oils it spoils easily and needs a preservative, usually mixed tocopherols. The levels used in food are a modest supplement, well below a therapeutic dose.

A plant fat high in medium-chain triglycerides, fats the body can burn quickly without the usual digestion steps. Those fats are the reason coconut oil appears in some senior and brain-support foods, where small studies of medium-chain fats in older dogs showed modest cognitive benefits; a food's coconut oil is a lower dose of the same fats. It supplies almost no essential fatty acids, so a food cannot rely on it as the only fat. It is calorie-dense and fine in the small amounts used.

A spice added for color and for its curcumin, a compound studied for anti-inflammatory effects. In people and lab animals curcumin is poorly absorbed unless paired with black pepper or fat, and the amounts in a pet food are far below those used in supplement studies. It is safe and gives kibble a warm color, which is most of what it is doing here; the joint and anti-inflammatory claims rest on doses far higher than a food provides.

A fruit added in small amounts for antioxidants and a bit of fiber. Blueberries are safe for dogs and cats, and the pigments that color them are the same ones linked to antioxidant activity in people. In a complete food they appear well down the list in small amounts, so they are a modest extra and should not decide which bag you buy.

A small fruit added mostly for its association with urinary health. Cranberry compounds can make it harder for some bacteria to cling to the bladder wall in laboratory studies, but there is no good evidence that the amount in a pet food prevents or treats urinary infections. At label levels, a small amount well down the list, treat it as a minor fruit that adds a little fiber and antioxidants.

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.

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.

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.

An extract added in tiny amounts for its antioxidant compounds, and in some dental treats for breath. The caffeine content is the only real question, since caffeine is toxic to pets in quantity; the extract is usually decaffeinated or used in amounts too small to matter. There is no evidence the levels in a pet food produce any health effect. It is a marketing ingredient, safe at food levels.

A culinary herb added in tiny amounts, usually with a claim about fresh breath. Parsley does contain chlorophyll and some vitamins, but there is no evidence that the fraction of a percent in a pet food changes breath or anything else. It is safe at these levels. It appears on some toxic-plant lists because very large amounts can cause light sensitivity; the pinch in a pet food is nowhere near that.

A leafy green added in small amounts for vitamins, minerals and color. Spinach is high in oxalate, which binds calcium and in large quantities is a concern for pets prone to calcium oxalate bladder stones. The amounts in a complete food are tiny, often a fraction of a percent, so for most pets it is a token vegetable with no nutritional or safety weight.

A dark leafy green, dried and added in small amounts, mostly for the vitamins and the look of the ingredient list. Kale is safe for dogs and cats at food levels. Like spinach it contains oxalate, and in quantity it is a consideration for pets prone to calcium oxalate stones, but the fraction of a percent in a complete food is not a factor. At these amounts it is there for the ingredient list and does not change the nutrition of the food.
