    Overall View

    Kirkland Signature is known for providing quality products, which is why it is a popular brand — this includes its dog food formulas too. The dog food is affordable and made with ingredients that can be pronounced and understood by a layperson. A variety of meats with healthy carbohydrates and other plant proteins makes for well-rounded dog food. Nature’s Domain has three all-life-stages of dry formulas, one organic option, a puppy formula, and two varieties of wet dog food.

    Who Makes Kirkland and Where Is It Produced?

    Kirkland Signature brand dog food is manufactured by Diamond Pet Foods. Diamond manufactures its own brand of dog food, as well as for many other companies. There are five factories located across the United States, and you will find Kirkland Signature dog food sold through Costco and a few varieties on Amazon.

    Which Types of Dogs Are Best Suited to Kirkland Dog Good?

    Nature’s Domain line has five dry food varieties and two wet dog foods, both of which are grain-free options. These are suitable for dogs who can’t have grain in their diets due to allergies and sensitivities. There are different flavors of meat, one for puppies, and an organic chicken recipe. The wet dog food offers a turkey and pea stew or organic chicken with vegetables.

    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. For example, a dog who suffers from kidney disease would do well with Blue Buffalo Kidney Support as recommended by a veterinarian. If you have a dog who is overweight and diabetic, then Hill’s Digestive/Weight/Glucose Management could be an option.

    Overview of Ingredients

    Calorie Breakdown:

    kirkland signature natures domain
    ** We chose to use Nature’s Domain Turkey Meal and Sweet Potato to represent the other products in the line for detailed recipe and nutrient analysis.


    Nature’s Domain recipes have a high-quality protein source within each recipe, which is good to reduce the chance of a meat allergy. The percentage of protein is 20% or above in all their  recipes, with many above 24%. With these grain-free diets, some protein is provided by added garbanzo beans, lentils, and peas.


    Depending on Nature’s Domain recipe, there will be different fat sources used — either canola oil, chicken liver, or salmon oil. All these provide plenty of energy, with salmon oil containing omega-3 fatty acids that strengthen the immune system and DHA, which is good for brain and eye development.


    Since Nature’s Domain is grain-free, the carbohydrates sources are derived from plants such as sweet potato, peas, and beet pulp to make sure your dog receives plenty of nutrients and energy.

    Controversial Ingredients

    • Canola oil: Canola can offer health benefits to a dog’s diet, proponents say. Critics, however, argue that salmon oil is a better choice for dogs.
    • Brewer’s dried yeast: It adds nutrients and protein to the dog foo, but can also be an allergen source for some dogs, which is why it is controversial. It is not included in every Nature’s Domain recipes.
    • Tomato pomace: This ingredient is a source of soluble fiber and provides other nutrients. However, some argue that it is used as a filler, even though it is seen in many high-quality dog foods.

    Recalls of Kirkland Dog Food

    In 2012, seven of the Kirkland Signature formulas were voluntarily recalled by Diamond Pet Foods for possible salmonella contamination; the recall included one Nature’s Domain recipe.
