    Overall View

    Kirkland dog food is an affordable food made with premium ingredients to offer whole-body nutrition. There are formulas catered to adults, puppies, seniors, and small breeds, as well as a weight management formula. The biggest advantage of buying Kirkland dog food is how affordable it is.

    Who makes Kirkland and where is it produced?

    Kirkland brand dog food is manufactured by Diamond Pet Foods. There are five factories located across the United States, and you will find Kirkland dog food sold through Costco, with some products available on Amazon (though many still aren’t).

    Which types of dogs is Kirkland best suited for?

    There are two lines of Kirkland dog food: the Kirkland Signature and the Kirkland Signature Natures Domain. Kirkland signature offers six varieties that include specialized formulas for adults, small breeds, puppies, seniors, and healthy weight formula. Canned formulas are offered in chicken and rice or lamb and rice.

    Nature’s Domain line has five dry food varieties and two wet foods that are all grain free. There are different flavor profiles: one formulated for puppies and an organic variety. The wet food is offered as an organic chicken with vegetables or a turkey and pea stew (not organic).

    Which types of dogs might do better with a different brand?

    Dogs who require a specialized diet because of a disease or other health concerns would benefit from a different brand. A dog who suffers from frequent bladder stones may benefit from Royal Canin Veterinary Diet Urinary SO dry dog food as recommended by a veterinarian. A dog who has memory concerns may need a more specialized diet, such as Purina Pro Plan Veterinary Diets Neurocare Adult Dog Food.

    Primary Ingredients in Kirkland Dog Food

    Kirkland Signature

    Kirkland Signature Dog Food Variety

    The main meat source used is chicken and chicken meal, which can be an allergen to some dogs. However, the lamb and rice formula for adult dogs could be used in place of the chicken if that’s the case.

    Whole-grain brown rice and pearled barley is a whole-grain and fiber source. Dried egg is added for protein and brewer’s yeast for antioxidants, but these can also be an allergen to some dogs. There are whole vegetables and fruits included, as well as chicory root and flaxseed. The wet food offers either chicken or lamb with liver and no fruits and vegetables, just added supplements.

    Nature’s Domain

    Kirkland Signature Nature's Domain Puppy Formula Chicken & Pea Dog Food

    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.

    Overview of Ingredients in Kirkland (Costco) Dog Food


    Kirkland does well at including high-quality protein sources and not adding too many varieties into one formula. This is good for reducing the chance of a meat allergy. The percentage of protein is 20% or above in all their recipes, with many above 24%. The chicken recipes use chicken and chicken meal for added protein.


    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.


    Complex carbohydrates provide energy and fiber to the food. Kirkland uses whole-grain rice, barley, and many plant sources, such as sweet potatoes, peas, and beet pulp, to make sure your dog receives plenty of nutrients.

    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.

    Recalls of Kirkland Dog Food

    In 2012 seven of their formulas were voluntarily recalled by Diamond Pet Foods for possible salmonella contamination.

    This is one of Kirkland’s most popular brands because it provides complete and balanced nutrition for all adult dogs. The three primary ingredients are lamb, lamb meal, and whole-grain brown rice, which are ideal protein sources, as well as being highly digestible.

    You will also find glucosamine and chondroitin to help support your dog’s joints and antioxidants to support overall health. For a strong immune system, the addition of omega-6 and -3 fatty acids is an ideal ingredient. It uses Active9 probiotics to provide live, active cultures that support healthy digestion. Thus, this formula is great for overall health.

    On the downside, it is not ideal for dogs with grain allergies because it contains brown and white rice. It also contains brewer’s yeast, so do not buy if your dog is immunocompromised, is prone to yeast infections, or has an allergy to yeast. However, many like that it does contain fruits, such as apples and cranberries, and vegetables, such as kelp and peas.

    Guaranteed Analysis:

    Crude Protein: 26%
    Crude Fat:  16%
    Moisture: 10%

It is enhanced with salmon oil that supplies DHA and omega-3 fatty acids to support brain and eye development. Antioxidants such as vitamin E and selenium also help keep your pup healthy. The kibble is small and easy to chew and boasts a tasty flavor.
