Everyone in the US and Canada knows Costco. Like Sam’s Club, it’s synonymous with offering affordable, high-quality products you can buy in bulk.
Yeah, we love the rotisserie chickens, too :)
Not only does Costco have its own gas pumps, credit card, and plenty of additional perks, it’s expanding worldwide. Apart from the 550+ stores in the US and 100+ stores in Canada, Costco can be found in Mexico, the UK, Japan, South Korea, Taiwan, Australia, Spain, Iceland, France, and even China.
Costco has a private label called “Kirkland Signature.” But unlike other private labels, Costco has gone to extreme lengths to keep quality as high or higher than name brands. One of the best examples is dog food.
When we set out to write a review of Kirkland dog food, we were skeptical at first (just like you might be). Let’s dissect the brand in more detail to dispel any myths or doubts.
Who Makes Kirkland Dog Food?
Some people may ask if Diamond Pet Foods makes Kirkland Signature dog food.
You’ll find most articles online say this is speculative, but we found proof — on Costco’s FAQ page. The second FAQ from the bottom states that all of the Kirkland Signature dry foods are made by Diamond Pet Foods in five US facilities (two in Arkansas and one each in California, Missouri, and South Carolina).
Granted, this doesn’t answer who makes the canned food, but it does confirm what has been speculated upon regarding the dry dog foods. One big hint that Diamond Pet Foods also produces canned (wet) food is the back of the canned food package label. It states that Nature's Domain trademark is owned by Schell & Kampeter Inc., which happens to own Diamond Pet Foods.
The long version is: the Kirkland Signature brand was introduced in 1992. It got its name from Costco’s former worldwide HQ in Kirkland, Washington. The current HQ is located in Issaquah, Washington, which, as you can tell, doesn’t have the same ring to it.
It turns out that many Kirkland Signature products are produced by well-known companies and branded under the Kirkland Signature umbrella. These products include food, household, pet, health, and clothing products. And also tires, auto essentials, office supplies, sporting goods, baby foods/products, home & kitchen products, among others.
For example, Kirkland Signature coffee is roasted by Starbucks (says so on the label). Kirkland Signature jelly beans are produced by Jelly Belly (also on the label), and the list goes on — from cups to baby formula and everything in between.
The reason Costco “co-brands” is to make customers more confident in the Kirkland brand. And that makes sense. At this point, we don’t think Costco’s private labels are looked down upon at all. Many people swear by them. This isn’t some mass delusion — Costco’s CEO has stated in interviews that the goal is to sell high-quality products at affordable prices.
Let’s explore the best offerings from the Kirkland Signature line of dog food.
Kirkland Dog Food Review
One of the first things that catch your eye when you look at dog food is the label “Super Premium.” It sounds high-end, and that is certainly the intention. However, to be fair and unbiased, we want to make it clear that labels like “premium,” “ultra-premium” and “super premium” are not required to contain higher-quality or a higher quantity of ingredients.
The FDA also states that “nor are they [labels like super premium] held up to any higher nutritional standards than are any other complete and balanced products.”
So super premium doesn’t technically mean anything. What does matter is the ingredients, guaranteed analysis, and the Kirkland brand dog food reviews from pet owners. We’ll go over each of these in the sections that follow.
As pet owners, we are told to look for the first five ingredients (especially the first ingredient). As we look through the best dog foods, you’ll notice a common trend — they all have meat as the first ingredient.

Kirkland Signature Adult Formula Chicken, Rice and Vegetable Dog Food
WHY YOU SHOULD BUY
The Kirkland Signature Adult Dog Chicken, Rice, and Vegetable is a balanced meal that contains high-quality proteins and carbs. The #1 ingredient is Chicken, and this dry food also contains vital nutrients and nutrients that support healthy joints.
Kirkland chicken dog food contains real chicken and excellent carbohydrates (whole-grain brown rice and cracked pearl barley). Unlike many dog foods containing Brewer’s rice (broken up fragments of rice), Kirkland Signature has only the best ingredients.
This dry kibble helps support three key areas of doggy health: the digestive system, joints, and the immune system. It includes pre- and probiotics to make digestion easier. It has Glucosamine and Chondroitin for joint health and Omega 3 & 6 fatty acids for immune system support.
The probiotics aren’t there to fill in space for the product description. They’re included as the Active9 Probiotics complex, which is live bacteria cultures. Apart from the ambiguous “Super Premium” label, everything else in this dog food is legit.
KEY FEATURES:
- First 5 ingredients: Chicken, chicken meal, whole grain brown rice, cracked pearled barley, chicken fat (preserved with mixed tocopherols)
- Includes: Calcium, Phosphorus, Zinc, Selenium, Vitamin E, Omega-6 Fatty Acids, Omega-3 Fatty Acids, Glucosamine, Chondroitin

SPECIFICATIONS:
- Type: Dry food
- Breed size: Large breeds
- Life Stage: Adult
- Weight: 40-pound bags
WHAT WE LOVED:
- Available in a large 40 lb bag
- 3 out of the first 5 ingredients are animal products
- At $40.99 for 40 lb, it’s very affordable
WHAT WE DIDN’T LIKE:
- Relatively high in calories compared to other dog foods
- The “Super Premium” label doesn’t mean anything
Kirkland Signature Adult Formula Lamb, Rice and Vegetable Dog Food
WHY YOU SHOULD BUY
Kirkland Signature’s Lamb, Rice & Vegetable Formula is like a balanced and nutritionally-varied feast made up of lamb meat, veggies, fruits, herbs, and important nutrients. Like other Kirkland Signature dog foods, it includes probiotics, antioxidants, and nutrients for healthy joints.
Many cheaper dog foods like to boast about their Lamb/Chicken/Beef or other main protein, while in reality, the animal protein isn’t in the top-3 ingredients. Kirkland Signature Lamb Formula is a lamb/rice kibble that’s heavy on the lamb and lighter on the carbs (you know, dogs need to watch their figure too).
The lamb flavor is prominent, and if your dog is a fan of lamb, they’ll go crazy for this formula when they hear the kibble hit the bowl. And in addition to the great taste, this dog food is plentiful in antioxidants, probiotics, minerals like Zinc and Selenium, and other nutrients.
Dog food, like human food, needs to have a certain level of fiber to move things along. Kirkland doesn’t disappoint the digestive health aspect either — fiber-rich ingredients like chicory, and a probiotic complex, aid digestion and help support a healthy digestive system.
KEY FEATURES:
- First 5 ingredients: Lamb, lamb meal, whole grain brown rice, ground white rice, rice bran
- Includes: Zinc, Selenium, Vitamin E, Omega-6 Fatty Acids, Omega-3 Fatty Acids, Glucosamine, Chondroitin
- 373 kcal/cup
SPECIFICATIONS:
- Type: Dry food
- Breed size: All breeds
- Life Stage: Adult
- Weight: 40-pound bags
WHAT WE LOVED:
- Lamb is the 1st ingredient
- Contains antioxidants, pre- and probiotics, and joint-supporting nutrients
- At a price point of $43.99 for a 40 lb bag, it’s a great value considering lamb is more expensive than chicken
WHAT WE DIDN’T LIKE:
- The “Super Premium” label doesn’t mean anything
Kirkland Signature Healthy Weight Formula Chicken & Vegetable Dog Food
WHY YOU SHOULD BUY
If your vet suggests that your dog be put on a weight loss diet, this Healthy Weight Formula is perfect! It’s a low-calorie dog food (275 calories/cup) with chicken meal as the 1st ingredient. It also includes L-Carnitine, which has been shown to aid in burning excess fat.
Kirkland Healthy Weight dog food is for pudgy pooches that need to lose a few pounds. Remember, you should consult with a vet before making significant changes in your dog’s diet (like switching to low-calorie dog food). A vet is qualified in dog nutrition and can help you develop a plan that includes diet and lifestyle changes.
Not all dogs are super active, and if your dog spends a lot of time indoors, they may be tipping the scale into the overweight or even obese category. With that in mind, Kirkland Signature created this low-cal doggie kibble for adult dogs. It has plenty of proteins and carbs, so it’s filling and tasty. And its nutrient-rich formula makes it ideal for supporting digestion, immune response, joint health, and a healthy skin and coat.
KEY FEATURES:
- First 5 ingredients: Chicken meal, brown rice, peas, cracked pearled barley, millet
- Includes: Zinc, Selenium, Vitamin E, L-Carnitine, Omega-6 Fatty Acids, Omega-3 Fatty Acids, Glucosamine, Chondroitin
- 275 kcal/cup
SPECIFICATIONS:
- Type: Dry food
- Breed size: All breeds
- Life Stage: Adult
- Weight: 40-pound bags
WHAT WE LOVED:
- Low-calorie but still complete and balanced nutrition
- The addition of L-Carnitine shows a deep level of research and understanding of fat metabolism.
- Lower in price at $38.99 for a 40 lb bag
WHAT WE DIDN’T LIKE:
- To keep calories low, the animal protein was downgraded to chicken meal (essentially ground up chicken bits)
- The “Super Premium” label doesn’t mean anything
Kirkland Signature Mature Formula Chicken, Rice and Egg Dog Food
WHY YOU SHOULD BUY
The Kirkland mature dog food recipe is a complete and balanced formula lower in fat than regular adult dog food and includes L-Carnitine to assist in fat metabolism and keep your mature friend’s weight in check. Contains a higher concentration of joint-supporting nutrients than standard Kirkland adult dog food.
As we already mentioned, you don’t need to look at the ingredients list when choosing from Kirkland’s Signature dog food. The products stated on the packaging are 1-for-1 in the order of appearance. In this case, it’s chicken, rice, and egg, in that order.
Chicken and egg proteins are easy to digest, a big plus in our book, especially considering this is for mature dogs. Also, the choice of carbs (whole grain brown rice, oatmeal, barley, and white rice) means your dog will have the energy (and fiber) to live a happy life.
As dogs age, they have different needs. One of those needs is supporting their joints. This dog food has more Glucosamine and Chondroitin than the standard adult dog version, and it’s these nutrients that support joint health. Also, this recipe has Omega 3 and 6 Fatty Acids, which keep the coat shiny and skin in good shape while also helping support a good immune response.
KEY FEATURES:
- First 5 ingredients: Chicken, chicken meal, whole grain brown rice, egg product, oatmeal
- Includes: Calcium, Phosphorus, Sodium, Zinc, Selenium, Vitamin E, L-Carnitine, Omega-6 Fatty Acids, Omega-3 Fatty Acids, Glucosamine, Chondroitin
- 339 kcal/cup
SPECIFICATIONS:

- Breed size: All breeds
- Life Stage: Senior
- Weight: 40-pound bags
WHAT WE LOVED:

- Contains additional minerals like Calcium, Phosphorus, and Sodium to support bones and teeth
- 3 out of the first 5 ingredients are animal products
- Affordable at $42.99 for a 40 lb bag.
WHAT WE DIDN’T LIKE:
- The “Super Premium” label doesn’t mean anything
Kirkland Signature Nature’s Domain Organic Chicken & Pea Dog Food
WHY YOU SHOULD BUY
Kirkland’s Signature Nature’s Domain Organic Chicken is the only USDA Organic dog food Kirkland produces. It’s grain-free and makes up for the absence of carbs from grains with various vegetables and legumes.
Nature’s Domain brand is exclusively grain-free. Kirkland grain free dog food is more expensive than the grain-inclusive formulas and comes in smaller bags depending on the recipe.
Almost every Kirkland Nature's Domain dog food review includes the Organic Chicken & Pea Dog Food. It’s the only USDA Certified Organic dog food produced by Kirkland, which makes it special. Not only is the first ingredient (real chicken) organic, so are the rest of the ingredients.
Apart from being complete and balanced, Nature’s Domain formulas are also lower in calories when compared to grain-inclusive recipes. This particular dog food has varied sources of Omega Fatty Acids, including canola oil, sunflower meal, and flaxseed.
To make up for the lack of grains, Kirkland used sweet potatoes, regular potatoes, peas, garbanzo beans, lentils, among others, to fill in the carb and fiber gaps. But again, these vegetables are all organic and provide balanced nutrition.
One important thing to keep in mind when switching to grain-free (or any dog food for that matter) is slowly introducing it into your dog’s diet. Read about the right way to switch dog foods on AKC’s website.
KEY FEATURES:
- First 5 ingredients: Organic chicken, organic peas, organic lentils, organic garbanzo beans, organic sweet potatoes
- Includes: Zinc, Selenium, Vitamin E, Omega-6 Fatty Acids, Omega-3 Fatty Acids
- 325 kcal/cup
SPECIFICATIONS:
- Type: Dry food
- Breed size: All breeds
- Life Stage: Adult
- Weight: 30-pound bags
WHAT WE LOVED:
- USDA Certified Organic
- The first 5 ingredients are all organic
WHAT WE DIDN’T LIKE:
- It’s the most expensive dog food Kirkland offers (at $49.99 for a 30 lb bag)
Kirkland Signature Nature’s Domain Turkey Meal and Sweet Potato Dog Food
WHY YOU SHOULD BUY
A grain-free formula with a turkey-first recipe that includes veggies, herbs, probiotics, and much more. Provides a complete and balanced meal that will energize, nourish, and support your dog throughout all of its life stages.
Kirkland Signature Nature's Domain Grain-Free Turkey Meal & Sweet Potato Formula offers great variety for a grain-free diet. According to reviews we read on Amazon, some dogs are partial to certain dog foods. So, Kirkland did the right thing by coming up with recipes that are nearly identical in nutrition but vary in taste and ingredients.
This blend of turkey, vegetables, and fruits provides everything your dog needs for all life stages. Your dog will jump for joy when you pop open the bag of kibble, and the inclusion of probiotics will keep you put your mind at ease, so you don’t have to worry about digestive issues. When switching dog foods, digestive issues may arise regardless of the ingredients. That’s why it’s important to transition your dog over to the new food gradually.
We weren’t able to find a Kirkland dog food feeding guide online, but you can find recommendations on the back of every bag of Kirkland dog food.
KEY FEATURES:
- First 5 ingredients: Turkey meal, sweet potatoes, peas, potatoes, canola oil
- Includes: Zinc, Selenium, Vitamin E, Omega-6 Fatty Acids, Omega-3 Fatty Acids
- 336 kcal/cup
SPECIFICATIONS:
- Type: Dry food
- Breed size: All breeds
- Life Stage: Senior
- Weight: 35-pound bags
WHAT WE LOVED:
- Grain-free recipe
- Contains vegetable sources of protein like peas
- Balanced and complete nutrition that includes meat, vegetables, and fruits
WHAT WE DIDN’T LIKE:
- Although the choice of Turkey Meal over Turkey is understandable (price matters), we feel that for a few dollars extra, most people wouldn’t mind the upgrade.
Kirkland Signature Nature’s Domain Salmon Meal & Sweet Potato Dog Food
WHY YOU SHOULD BUY
Nature’s Domain Salmon Meal & Sweet Potato Formula is a fishy feast with plenty of veggies and fruits to provide balanced nutrition. The grain-free recipe is ideal for all stages of life, from puppy to mature dog. Includes a blend of Omega 3 &6 Fatty Acids for a healthy nervous system and fat metabolism.
Kirkland Salmon dog food is formulated for all stages of life. It might sound fishy, but trust us, dogs love fish just as much as cats. Plus, considering that other ingredients have healthy fats, like canola oil and fish oils, it will taste amazing, and you’ll be surprised how fast your dog wolfs it down.
Grain-free isn’t considered to be better than grain-inclusive. However, for dogs with grain sensitivity or allergies. If you’re worried your dog might be allergic to grains, check out PetMD for food allergy symptoms. Also, make sure to consult with your vet before switching to different dog food.
The Salmon Meal recipe has a similar concentration of fatty acids, probiotics, and antioxidants as the rest of Nature’s Domain line. Coming in at a slightly higher price point ($43.99) than the Turkey Meal recipe ($41.99).
KEY FEATURES:
- First 5 ingredients: Salmon meal, sweet potatoes, peas, potatoes, canola oil
- Includes: Zinc, Selenium, Vitamin E, Omega-6 Fatty Acids, Omega-3 Fatty Acids
- 336 kcal/cup
SPECIFICATIONS:
- Type: Dry food
- Breed size: All breeds
- Life Stage: All life stages
- Weight: 35-pound bags
WHAT WE LOVED:
- Grain-free for dogs with allergies or sensitivities
- Well-balanced and nutritious
- Includes a variety of vegetables and fruits in addition to salmon and ocean fish meal
WHAT WE DIDN’T LIKE:
- Although the choice of Salmon Meal over Salmon is understandable (price matters), we feel that for a few dollars extra, most people wouldn’t mind the upgrade.
Kirkland Canned Dog Food
As we discussed in the section on Who Makes Kirkland Signature, the canned dog food is likely produced by Diamond Pet Foods, making the dry food.
But we found it odd that there’s only one choice for canned food currently available:
- Kirkland Signature Nature's Domain Canned Dog Food, Turkey & Pea
It comes in a 24-count pack of 13.2 oz cans. The first five ingredients are Turkey, turkey broth, vegetable broth, natural flavor, and dried egg product. Beyond it being suitable for all life stages (including pregnant/nursing moms and puppies), having 356 kcal/can, and being grain-free, there’s not much information about it.
Kirkland canned dog food was also available in Organic Chicken, Chicken, and Lamb recipes in the past.
Kirkland Dog Food Ingredient List
We’ll go over some of Kirkland dog food ingredients that you may not have seen before. To see a full glossary of ingredients, check out Costco’s website.
Active9 probiotics are a complex of “canine-specific probiotics” developed for Kirkland Signature. The special formulation includes bacteria that are vital for a dog’s digestive health. They include Lactobacillus acidophilus, Bifidobacterium animalis, Lactobacillus reuteri.
Chicory root- A prebiotic. Think of it like this: a prebiotic is the optimal environment for good bacteria, and probiotics are the good bacteria themselves. Both are required for optimal digestion.
Chondroitin Sulfate and Glucosamine hydrochloride - Support joint health by repairing and protecting cartilage.
L-Carnitine - A vital nutrient for fat metabolism. It helps the body burn fat and maintain muscle mass.

Kirkland senior dog food (as do other dog foods for mature dogs) contains less fat.
There’s no Kirkland large breed dog food, but the Kirkland small dog food interestingly has some unique qualities. Small-breed dog food contains Taurine and L-Carnitine. Dogs produce their own Taurine. However, sometimes they require supplementation. Just to be clear, the amount in the small-breed dog food is not significant.
The addition of L-Carnitine is interesting, and we can only guess that it’s because some people tend to overfeed or overestimate how much small dogs need to eat.
Kirkland Brand Dog Food Recalls
Kirkland dog food quality is comparable to any of the big-name brands. Considering it’s produced by Diamond Pet Foods, a company with many years of experience, this doesn’t come as a surprise.
Be that as it may, everyone slips up now and then. In the last 20 years, there have been two recalls:
- 2012 - A potential Salmonella contamination spurred a recall by the FDA. It was only in 2016 when a class-action lawsuit was settled (without a direct admission of guilt from Kirkland/Diamond). Of course, Salmonella is no joke, and according to the lawsuit, some cases were fatal.
- 2007 - A potential melamine contamination in Kirkland Signature 2-Flavor canned dog food and many other pet foods caused a massive recall issued by the FDA.
Conclusion
Looking past the “Super Premium'' labels and marketing buzzwords, we feel the most important lesson you can learn about Kirkland Signature is the Costco CEO’s attitude. He aims to make higher-end products cheaper for the average consumer.
And Costco has managed to do this with Kirkland adult dog food and the other life-stage specific formulas. Unlike lower-shelf brands that spend tons of money on marketing and hype, Kirkland Signature spends its money on improving the formula and including only the best ingredients.
Yes, admittedly, there have been a few recalls, but the last one was nearly a decade ago. Plus, if you look at the reviews, you’ll see that every recipe has a rating higher than 4 out of 5 stars.
We give Kirkland dog food two big paws up!
FAQs
Kirkland super premium dog food has high-quality ingredients. Animal products are always the #1 ingredient, and there have only been two recalls for Kirkland Signature dog food. The dog food line comes in grain-inclusive and grain-free recipes, including canned food.
According to Costco’s FAQ, Kirkland Signature dog food is produced by Diamond Pet Foods in the USA. The company has five facilities, mostly in southern US states.
You can buy Costco Kirkland dog food in Costco and on Amazon. However, the dog food on Amazon is almost twice as expensive as Costco. You’d be better off buying a yearly Costco membership to save money. Plus, Costco has many other products you can buy in bulk to save even more money.
Pet owners highly praise Kirkland Signature. In our opinion, it’s a great choice as it’s relatively inexpensive and has ingredients you don’t find in high-end pet foods like probiotics, Omega Fatty Acids, and Glucosamine/Chondroitin. Our Kirkland dog food rating is 4.5/5.
