Ingredient Quality

Evalutation Criteria

Product is calculated to contain 55% carbohydrate ^ⓘDogs have no nutritional requirement for carbohydrate but they are used for energy, texture and taste. Starch is also required for extrusion in dry foods. Excessive carbohydrate is an indicator of food quality as it can be used to reduce manufacturing cost. Foods that are high in carbohydrate can raise insulin and cause obesity. Some studies also show that dogs fed a high carbohydrate content have changes to their gut bacteria. Learn more
Contains low quality fiber ^ⓘDogs have no known need for fiber, but soluble fiber is fermented by gut bacteria, which supports gut health. Cellulose is an insoluble fiber made from wood pulp and is the least expensive and least functional form of fiber since it's very poorly fermented. It is included to firm stools. Learn more
Is fortified with excessive vitamins ^ⓘWhen vitamins come from whole food sources, they include the full spectrum of cofactors, which makes them safe and bioavailable. While a couple of added vitamins are acceptable, five or more implies the food is of poor nutritional value. Learn more
Product contains two or more added amino acids ^ⓘMultiple amino acids are typically only found in lower quality foods that rely on less complete plant sources of protein. Learn more
Is fortified with excessive minerals ^ⓘFive or more added minerals indicate a lower quality food that’s lacking naturally occurring minerals from whole food sources.

Evalutation Criteria

Studies shows that ultra processed foods are linked to a higher rate of all-cause mortality in humans. Learn more
Contains known GMO ingredients in the top 5 ingredients including corn and soy ^ⓘThere are limited safetey studies on geneticaly modified and Roundup Ready crops although they are lacking in nutrients compared to non-GMO foods. GMO crops also strip nutrients from soils, require increased pesticide risk and may be involved in bee die-off. Learn more
Contains natural flavor ^ⓘNatural flavors are often animal digest or MSG, which are low quality ingredients with limited safety studies. Learn more
