There is no established Great Pyrenees-specific need for grain-free food. The FDA says the connection between diet and non-hereditary canine dilated cardiomyopathy (DCM) remains unknown; reports have involved both grain-free and grain-containing diets. Choose a complete, appropriate food for your dog’s life stage and health needs, and ask your veterinarian before making a diet change.
Do Great Pyrenees need grain-free food?
No source establishes that Great Pyrenees need a grain-free diet or receive a breed-specific benefit from one. “Grain-free” is not, by itself, evidence that a food is healthier, more natural, or safer. That does not mean every food is equally suitable: the dog’s life stage, nutritional needs, and health history still matter.
Grains are not required for every dog, and a grain-free diet is not automatically harmful. If your dog has a diagnosed food allergy or another medical reason for a particular diet, follow the plan made with the treating veterinarian rather than changing foods based on a general rule.
What does the FDA say about grain-free food and DCM?
The U.S. Food and Drug Administration says, “The FDA does not know the specific connection between these diets and cases of non-hereditary DCM.” The agency has received reports involving both grain-free and grain-containing diets, so the available information does not establish that grain-free food as a whole causes DCM or that grain-inclusive food prevents it.

Many diets associated with reported cases included non-soy pulses—such as peas or lentils—high on the ingredient list. The FDA notes that pulses have been used in pet foods for years and that there is no evidence they are inherently dangerous; their role in the reported cases remains unclear. The agency says it is also exploring possible contributions from genetics, underlying medical conditions, and other factors.
FDA adverse-event reports can help identify a potential signal, but report counts alone do not establish cause and effect or show how common a condition is among dogs eating a particular food. The investigation overview describes reports involving foods with peas, lentils, other legume seeds (pulses), and/or potatoes among the main ingredients, while cautioning that the reports are not enough to establish causality.

How to compare foods for your Great Pyrenees
Compare the food’s suitability for your dog, not just whether the package says “grain-free.” WSAVA’s nutrition resources can help you interpret label information and evaluate pet foods; they are a selection aid, not a certification of any particular brand. Use WSAVA’s nutrition guidelines.
- Life stage and intended use: Check that the food is appropriate for your dog’s life stage and that its nutritional adequacy statement matches the intended use.
- Individual health needs: If your dog has a diagnosed condition, suspected food allergy, or a veterinarian-prescribed diet, ask the treating veterinarian which foods fit the plan.
- Manufacturer information: Consider whether the manufacturer can answer questions about who formulates the food and what nutrition expertise supports it.
- Dietary claims: Treat “grain-free” as a description of the formula, not proof of a health benefit or a guarantee of safety.
When to involve your veterinarian
Discuss a planned diet change with your veterinarian, especially if your dog has a medical condition or you are considering a specialized diet. The FDA recommends veterinary discussion and notes that your veterinarian may consult a board-certified veterinary nutritionist for individualized advice. Do not stop a prescribed diet or attempt to diagnose a problem from ingredient lists alone. If your dog has symptoms or a diagnosed condition, contact the veterinarian managing their care.
