Ingredient Quality

1 out of 10

  • Product is calculated to contain 62% 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 fats that are highly processed or inflammatory Seed oils, such as safflower, sunflower or flaxseed oil, provide calories and taste. They are rich in omega-6 fatty acids, which can cause systemic and gut inflammation. Other oils like soybean are highly processed and may contain trans fats. Studies shows that ultra processed foods are linked to a higher rate of all-cause mortality in humans. Learn more
  • Contains unspecified animal sources, which are a less expensive source of meat While protein from animal sources is an important ingredient that’s highly digestible, the animal source should be named. You will want to see beef, salmon or chicken, not animal, fish or poultry. Unnamed protein sources are of much lower quality, especially meals, which are typically from rendered waste. 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.

Ingredient Safety

4 out of 10

  • Product is highly processed Canned foods are heated before and during canning, which will cause significant losses in some active enzymes, vitamins, amino acids and phytonutrients. Learn more
  • Contains known GMO ingredients in the top 5 ingredients including potatoes 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 ingredients known to contain higher pesticide/herbicide residues including soy Pesticides, herbicides and fertilizers pose a significant health risk to plants, animals and soils. Foods with the largest reported amount of residue will be penalized, including crops that are known to be spray-dried with glyphosate. Learn more

Other Concerns

Notable product facts

  • Omega-6 to omega-3 ratio is not provided. Diets rich in omega-6 fats can cause chronic inflammation and disease. Learn more
  • Product doesn't specify whether the fish is farmed or wild caught Farmed fish is less nutritious than wild caught fish and does not contain the same healthy fatty acid balance. Fish farming also threatens wild fish species. Learn more
