Grain-free dog food: genuine progress or clever marketing?
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
The grain-free aisle has kept growing in recent years, driven by a seductive pitch: dogs descend from wolves and have no use for grains. The reality is more nuanced, and Planète Pets helps you sort it out before you pay a premium. This guide complements our dog food section.

What “grain-free” actually means
A grain-free kibble contains no wheat, corn, rice or barley. But that doesn’t make it carbohydrate-free: manufacturing kibble requires starch, replaced here by potato, sweet potato, peas or lentils. Grain-free therefore does not mean low-carb, and certainly not 100% meat.
True or false: the myths under the microscope
- “Dogs can’t digest grains”: false. Domestication has given dogs a genuine ability to digest cooked starch. Well-cooked rice is highly digestible.
- “Grain allergies are common”: mostly false. Canine food allergies more often involve animal proteins (beef, chicken, dairy) than wheat. Only an elimination diet run with a vet allows a reliable diagnosis.
- “Grain-free means more meat”: sometimes true. Some brands, such as Orijen, do combine the absence of grains with a high proportion of animal ingredients. Others simply swap corn for peas, with no meaningful nutritional gain.
The real hallmarks of a good kibble
Rather than fixating on the presence or absence of grains, study the ingredient list: a named animal protein source in first position, a protein level consistent with the dog’s activity, quality fats and a reasonable ash content. Detailed disclosure of by-products and the country of manufacture matter too. For a puppy, the requirements are stricter still: see our guide to the best puppy food.
How big is the price gap?
Grain-free comes at a cost: expect €60 to €90 for an 11 to 12 kg bag in the premium range, versus €40 to €70 for a conventional kibble of comparable quality. That gap is only justified if the overall composition is genuinely superior. A cheap grain-free is still a cheap food.
Our Planète Pets verdict
Grain-free is neither a miracle nor a scam: it’s a sound option for some dogs, notably those whose intolerance has been confirmed by a vet, and superfluous for many others. If digestive or skin issues persist, see a vet before cycling through foods. And to slow down a dog that wolfs its ration, whatever it is, our comparison of slow-feeder bowls will come in handy.
