Ingredient Quality

0 out of 10

  • Product is calculated to contain 58% 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
  • Product contains ingredients that are high in sugar including dextrose and sugar Sugar is often found in pet food to increase the palatability or as a preservative or humectant. It is a low quality ingredient that can cause unwanted gut changes, obesity and insulin spikes. 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
  • 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 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
  • 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.
  • Product contains ingredients that are high in sugar including dextrose Sugar is often found in pet food to increase the palatability or as a preservative or humectant. It is a low quality ingredient that can cause unwanted gut changes, obesity and insulin spikes. Learn more

Ingredient Safety

5 out of 10

  • Product is ultra processed Extruded foods are heated four separate times during production, which will cause major losses in some active enzymes, vitamins, amino acids and phytonutrients. Studies shows that ultra processed foods are linked to a higher rate of all-cause mortality in humans. Learn more
  • Contains rice Arsenic contamination is a significant concern with rice since it naturally absorbs arsenic and the water it's grown in can be contaminated with arsenic. Arsenic is linked to chronic health issues. Learn more
  • Contains natural flavor Natural flavors are often animal digest or MSG, which are low quality ingredients with limited safety studies. Learn more
  • Contains ingredients known to contain higher pesticide/herbicide residues including beets 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
