Earthborn HolisticEarthBites Chewy with Lamb Protein

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 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.

Starch from the cassava root, used to bind kibble and as a carbohydrate source, especially in grain-free foods. It is nearly pure starch with little protein, fiber or micronutrients, and it is one of the least likely ingredients to trigger an allergy. A food that leans on tapioca for carbohydrate is getting easy digestibility and little else from it, which is fine as long as the rest of the recipe carries the nutrition.

A plant source of omega-3 fat (alpha-linolenic acid) and fiber, used in about a third of dog foods for coat and stool quality. Dogs and cats convert plant omega-3 to the useful forms inefficiently, so fish oil does the job better. Flax is not a documented common allergen, though some pets tolerate it poorly, most often as loose stool. Fine in a food; not a reason to prefer it over one using fish oil.

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 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 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 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 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 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.
