Best Grain-Free Dog Kibble in Canada

Grain-free dog food has become one of the most misunderstood categories in pet nutrition. Some pet parents choose it to avoid fillers or food sensitivities, while others hesitate due to ongoing fears around diet-related heart disease. Unfortunately, most online rankings add to the confusion by relying on opinions, sponsorships, or vague “vet-recommended” claims.

To cut through the noise, we reviewed 60 dog food brands and 103 kibble formulations sold across Canada and the United States. This article focuses exclusively on grain-free dry dog food and evaluates each formulation based on ingredient integrity, processing methods, protein digestibility, and manufacturing transparency, not marketing language.

This guide is part of our broader Best Dog Kibble in Canada review, where we compare grain-free, grain-inclusive, and specialty diets side by side.

What Defines a High-Quality Grain-Free Dog Kibble?

Removing grains does not automatically make a dog food healthier. In fact, many grain-free dog kibble simply replace grains with equally problematic starches such as peas, lentils, or potatoes. The best grain-free foods distinguish themselves not by what they exclude, but by what they prioritize: meat-based protein, whole-food nutrition, and minimal reliance on synthetic vitamin premixes.

In our evaluation, grain-free dog kibble scored highest when they were formulated with identifiable animal proteins, moderate carbohydrate levels, and processing methods that preserved nutrients. Brands that relied heavily on ingredient splitting, plant-based protein boosters, or vague meat sources scored significantly lower.

The Best Grain-Free Dog Kibble Brands in Canada

Across the grain-free category, a consistent pattern emerged. Smaller and mid-sized manufacturers generally used higher-quality ingredients than multinational pet food conglomerates. Brands such as Orijen and Acana rank near the top due to their high meat inclusion and comparatively lower carbohydrate loads.

Sunday Pets, Coevo and Petkind also performed strongly, particularly in ingredients and nutritional labelling.

While no grain-free dog kibble is perfect, these brands consistently outperformed competitors that relied on aggressive marketing rather than measurable nutritional quality.

Grain-Free Does Not Mean Low Carbohydrate

One of the biggest misconceptions among pet parents is assuming grain-free foods are naturally low in carbohydrates. Our data showed this is not always the case. One of the grain-free formulas, Bixbi Rawbble Liberty exceeded 35 percent carbohydrates on a dry matter basis, largely due to heavy use of legumes.

Carbohydrates are cheaper to source, easier to store, and help manufacturers maintain profit margins. However, high carbohydrate loads reduce protein bioavailability and may contribute to digestive issues, weight gain, and inflammation over time. For this reason, we recommend choosing grain-free dog kibble that keep carbohydrate levels under 35 percent whenever possible.

Why Protein Digestibility Matters in Pet Food

Protein percentage on a dog food label does not reflect how much protein your dog actually absorbs. Digestibility determines how much of the listed protein is biologically available and usable by the body. A dog eating a highly digestible food will absorb more nutrients and produce smaller, firmer stools, while poor digestibility often results in large stool volume and nutrient loss.

Only two of the 103 kibble formulations we reviewed publicly disclosed protein digestibility data. This lack of transparency allows manufacturers to use crude protein, including plant proteins or inferior animal byproducts.

Grain-Free Dog Food and DCM: Separating Fact From Fear

Concerns about grain-free diets and dilated cardiomyopathy (DCM) continue to influence feeding decisions, despite the lack of definitive evidence. The FDA has acknowledged that it does not know what causes non-hereditary DCM, and grain-free diets alone have not been proven responsible.

More recent investigations have revealed financial ties between some vocal DCM advocates and manufacturers of grain-inclusive pet foods. While this does not invalidate all concerns, it underscores the importance of evaluating evidence critically rather than reacting to fear-based headlines.

From a nutritional perspective, dogs do not require grains to meet their dietary needs. What matters most is overall formulation quality, amino acid balance, and nutrient bioavailability. If you’re still unsure, we break down the pros and cons in our grain-inclusive dog food rankings.

Other Reasons to Avoid Grain in Kibble

Corn in Pet Food: Digestive Sensitivities, Aflatoxin Risk and Low Biological Value

• Although dogs are adaptable to carbohydrates, corn is just not a good biologically appropriate ingredient for dogs. As a pet food flavour manufacturer says “Cats and dogs are not grain eaters by choice.“
• Also, some dogs tend to have sensitivities to corn.
• Lastly, grains in general if not stored well which is more than possible in pet food manufacturing can lead to aflatoxins. See FDA warning here about aflatoxins.
  • The results can range from liver damage to death. If you think, it is not likely, here are examples from the FDA in 2020. “FDA notified the public about potentially fatal levels of aflatoxins in multiple recalled varieties of Sportmix pet food manufactured by Midwestern Pet Foods, Inc. As of December 30, 2020, FDA is aware of at least 28 deaths and 8 illnesses in dogs that ate the recalled product.” Also “In September 2020, Sunshine Mills announced a recall of certain pet food products …. Shortly after, FDA determined that additional products made with the same corn may contain unsafe levels of aflatoxins and in October, Sunshine Mills expanded its recall to include additional products.”

Gluten in Kibble: Label Protein Inflation and Allergy Risk

• Similar to the bullet above, gluten is not a natural food for dogs or cats. It is a protein naturally found in grains including wheat and barley.
• The reason why pet food manufacturers add this to pet food is a low cost way to increase the protein value on the ingredient label. If anything, you should be very worried as the Melamine case which poisoned pets was due to this ingredient.
• In addition, some dogs have allergies/ food sensitivities to the gluten or grains with gluten. It can lead to digestive issues as well as itching, hot spots and chronic ear infections.
• Lastly, grains in general if not stored well which is more than possible in pet food manufacturing can lead to aflatoxins. See FDA warning in Corn bullet about aflatoxins.

Brewer’s Rice in Kibble: Low-Value Filler With Heavy Metal Concerns

• We call Brewers’ Rice basically leftover rice. After the milling process, the small fragmented pieces left are used in pet food.
• Although it is commendable that there is no food left to waste, rice is not a biologically appropriate, can cause blood sugar spikes and brewer’s rice lacks the vitamins, minerals and fiber found in whole grains.
• Pet food manufacturers add this as a cheap source of protein, carbohydrate and trace minerals.
• Rice also naturally contains arsenic so if your dog is eating food that has brewers’ rice high in the ingredient panel, your pet is accumulating arsenic toxins.
• Rice like corn and wheat is susceptible to aflatoxins and can poison your pet.

Common Pitfalls in Grain-Free Kibble Formulation

Many grain-free dog kibble lost points in our scoring system due to questionable formulation practices. Ingredient splitting was one of the most common issues, where peas, lentils, and pea protein are separated on the label to disguise their cumulative dominance. Excessive reliance on potato and plant-based protein sources also negatively affected rankings.

Legumes remain controversial. While not conclusively linked to disease, they are far from ideal when used as primary protein contributors. Grain-free foods that derived more than half of their protein from plant sources performed poorly overall.

Best Grain-Free Dog Kibble Review (2026)

Choosing a grain-free dog kibble isn’t about removing grains alone. In our research, the strongest grain-free options consistently relied on better ingredients as the nutritional foundation, used less carbohydrates as a binder, and avoided unnecessary synthetic additives. The following brands stood out not because of marketing claims, but because of good nutrition.

Note that to control for the variety of proteins, we settled on mostly the chicken based formulations of these pet foods. The kibble had to be adult or all life-stage formulations. The following were the chicken based but the whole line will work for you.

1. Orijen Grain-Free Kibble Review – #1 for All Dog Kibble

Orijen grain-free remains one of the most biologically aligned grain-free kibbles available in Canada. Its recipes are built around fresh and raw animal ingredients. For 3 years in a row, this has been ranked as #1 in terms of dog kibble in Canada and the USA.

Within this line, you will find the Orijen Original which is great for dogs without allergies, Orijen Six Fish which is perfect for dogs with dry skin issues and allergies to poultry. There is also the Orijen Regional Red which features red meat proteins and Orijen Tundra.

This is the line of dry dog food that we often recommend for active dogs or those transitioning off lower-quality kibble.

2. Sunday Pets Dog Kibble Review

Sunday Pets stands out for how it’s made. Instead of high-heat extrusion, the food is gently baked, helping preserve nutrients that are often lost during processing. This brand snuck out of New Zealand to take the 3rd spot in the overall dog kibble out of the blue. It’s especially well-suited to dogs with sensitive digestion as they use tripe in some of the formulations.

3. Coevo’s FD+K Dog Kibble Review

Coevo’s FD+K blends traditional kibble with freeze‑dried raw inclusions to give dogs the flavour and nutrient density of raw meat with the convenience of dry food. It’s especially worth considering if your dog responds well to mixed‑format foods that combine crunchy kibble with nutrient‑rich raw inclusions. The guaranteed analysis on most FD+K recipes shows about 34% protein on an as fed basis, which is solid for an adult dry food with added raw inclusions. They tried to live up their name of Coevolution.

4. Acana Grain-Free Highest Protein Dog Kibble Review

Acana Highest Protein Formulations offer a more affordable grain-free option for pet parents upgrading from other brands. It includes multiple animal protein sources and avoids many of the low-value fillers common in mass-market food. As a sister brand to Orijen, it delivers many of the same formulation principles of trying to be biologically appropriate at a more approachable price point.

Within this range, Acana Wild Prairie suits dogs without known food sensitivities, while Acana Pacifica is ideal for dogs with dry skin or poultry sensitivities that benefit from a fish-based diet. Acana Ranchlands focuses on red meat proteins, and Acana Grasslands offers a broader mix for dogs that tolerate multiple protein sources.

In addition, Acana has the Limited Ingredient formulations for dogs with known food sensitivities. These formulations go even further by having only a single ingredient protein such as the Acana Singles, Duck with Pear Recipe or the Acana Singles, Pork with Squash Recipe.

5 & 6. PetKind Tripe Dry Dog Kibble Review

PetKind takes a different approach by centering its recipes around green tripe, a naturally nutrient-dense and highly digestible ingredient. PetKind took the 5th and 6th spot due to their formulas for Single Animal, Poultry Free Protein and their Classic Series Tripe mixed line.

In their Tripe Dry line, we carry their Poultry-Free line and only two of the Classics Series (which contain chicken). Out of the Classics line, we have their Bison and Wild Salmon line which were proteins not represented in their Poultry-Free line. We found it to be redundant and not useful to carry their lamb or beef formulation in the classics because they had a better formulation in their Poultry-Free Line which were Single Animal Protein Lamb or Single Animal Protein Beef.

Dogs with food sensitivities or picky appetites often do exceptionally well on these formulas. The strong smell is typical of tripe-based diets, but for many dogs, that’s exactly what makes it appealing.

7. Canadian Naturals Omega Fresh Dog Kibble Review

We heard about Canadian Naturals from a reader of our blog and they wanted us to assess Canadian Naturals. The Canadian Naturals Omega Fresh line was a big surprise for us. The ingredient panel and protein % were good. We’d have to point that they also use quite a bit of legumes and that shows in not only their carbohydrate content but had an impact on their protein %.

We have to note that there is some amount of marketing deception here because the fruits and vegetables on their panel are after salt, which means less than 0.3% of the total formula are these ingredients. See our Salt Divider Rule for more explanation.

Despite, this the Omega Fresh ranked in our top 10. They have only 2 Skus in this formulation which are the Chicken and the Angus Beef. The other formulations of Canadian Naturals included in our review were NOT AS GOOD and placed in the mid-lower portion of 103 formulations.

8. Nature’s Logic Distinction Grain-Free Dog Kibble Review

A lot of pet owners are unaware of Nature’s Logic but they are a powerhouse in terms of pet kibble. Like Carna4, Nature’s Logic has managed to build 1 of the only 2 wholefoods-based kibble in the world that we know of. No synthetic ingredients just good formulation. The Distinction line has two formulations that are grain-free.

Nature’s Logic Distinction Grain-Free Land & Sea Recipe is a blend of beef and pollock, menhaden fish meals, along with dried vegetables, dried fruits, probiotics, and digestive enzymes. As the name suggests, this is their surf and turf line so it is good for dogs that do not have any known food sensitivities.

The only other distinction formulation that is grain-free is the Nature’s Logic Distinction Grain-Free Fowl Recipe. It is basically a poultry blend of chicken, turkey, duck and fish. This is their offering for dogs that love poultry and have no chicken allergies.

9. Bixbi Rawbble Liberty Grain-Free Dog Kibble Review

We have used Bixbi RAWBBLE freeze-dried but had not really considered their dry dog food before. However, stacked against over 100 other formulations, we were pleasantly surprised. They were one of the two brands that provided protein digestibility information upon deeper dive. While it still uses legumes like most grain-free kibble, the overall formulation is far more thoughtful than many competitors in this category.

10. Stella & Chewy’s Wild Red Raw Coated Grain & Legume Free Dog Kibble Review

Stella & Chewy’s Wild Red Raw Coated Dog Kibble is similar to the Coevo line in that there is freeze-dried. The difference lies in that instead of freeze-dried nuggets added, each kibble is coated with freeze‑dried raw meat.

Stella & Chewy’s Wild Red Raw Coated includes chicken, turkey, quail, guineafowl, goose, and duck, which together supply a high percentage of animal‑derived protein. The formula also uses a grain‑free, legume‑free approach and instead uses tapioca with no potatoes, peas, or lentils which made it to rank in the top 10.

Other lines of Stella & Chewy’s did not score as well and we would recommend this line over their other formulations. Dogs that tend to be picky may like the freeze-dried coating of this kibble.

Improving Your Dog’s Diet on Grain-Free Kibble

Even the best grain-free dog kibble benefits from thoughtful supplementation.

• Adding omega-3 fatty acids from fish or krill oil supports heart, skin, and joint health.
• Lightly soaking kibble with water or bone broth improves hydration and digestion. It may also help your pet’s kidneys long-term.
• Probiotics or fermented goat milk can further enhance gut health, while rotating protein sources reduces the risk of food sensitivities over time.

These practices help mitigate the inherent limitations of dry food while preserving its convenience.
