Dog Food At Costco Reviews

Nature’s Domain

These are grain-free formulas suited for dogs with allergies and other sensitivities. The main protein source is either beef, salmon, turkey, or lamb. Complex carbohydrates such as sweet potatoes, peas, and potatoes provide plenty of energy. You will find vegetables and fruit in this line, though not as much. The wet food offers either a turkey or chicken recipe that includes plenty of vegetables and other supplements.

Both lines add the Active9 probiotics to some of their recipes to provide live cultures that support healthy digestion. Antioxidants are included for overall health, and omega-6 and omega-3 fatty acids help maintain a shiny coat and support the immune system.

All of the formulas meet the AAFCO Dog Food Nutrient Profiles for All Life Stages and/or maintenance.

Controversial Ingredients

  • Canola oil: Many argue that canola oil is unsafe as well as being toxic, but some say that it can provide health benefits such as lowering cholesterol and blood pressure.
  • Brewer’s dried yeast: This is controversial if your dog has allergies. Otherwise, it adds nutrients and protein to the dog food.
  • Tomato pomace: This ingredient is included in the Nature’s Domain line. It can be used as a filler or a source of soluble fiber. Typically, lower-quality foods will use it as a filler, and it depends on the quality of the tomato as to how much nutrients it provides.
  • Fats

    Depending on the recipe, there will be different fat sources used — either canola oil, chicken liver, or salmon oil. All these provide plenty of energy, and some contain omega-3 and omega-6 fatty acids or DHA.
