Can dogs eat peas?
The full picture
Peas are a common ingredient in dog food and are safe for most dogs in moderation. They're a good source of plant-based protein, fibre, and various vitamins. Fresh, frozen, or steamed peas are all fine — avoid tinned peas (high sodium) and anything cooked with butter or seasoning. Dogs with kidney problems should avoid peas due to their purine content, so check with your vet first if that applies. Pea pods are generally fine but can be a choking hazard for small dogs.
Risks to watch for
- Purines may affect dogs with kidney issues
- Salt in tinned peas
Potential benefits
- Plant protein
- Fibre
- Vitamin A, K, B vitamins
Hidden sources to check
- Tinned mixed vegetables and soups — often contain onion or high salt levels alongside the peas
- Ready-meal side dishes (mushy peas, pea and mint purée) — usually seasoned, buttered, or sugared, not the plain peas the "safe" verdict applies to
- Grain-free dog food and treats — see the DCM note below; peas themselves aren't the issue, but check what a "grain-free" label is actually replacing the grain with
Peas, grain-free diets, and canine heart disease — what the evidence actually shows
This is a separate issue from an individual dog eating a few peas as a treat, but it's worth understanding if peas are a regular part of your dog's diet through their food. Between 2014 and 2019 the FDA investigated a rise in reports of dilated cardiomyopathy (DCM) — a serious heart condition — in dogs eating grain-free diets, and found that roughly 93% of the diets involved contained peas and/or lentils as a primary ingredient. Golden Retrievers, Labradors, and mixed breeds without a known genetic predisposition to DCM were disproportionately represented, which is what made the pattern notable rather than coincidental.
Importantly, the FDA has been explicit that this is not a proven causal link — testing of the diets involved found no abnormalities in nutrient levels, taurine, or amino acids, and the agency describes it as "a complex scientific issue that may involve multiple factors" that remains under investigation. This is about grain-free commercial diets built heavily around peas/lentils as a primary protein and starch source, not about giving your dog a spoonful of peas as an occasional treat — the two aren't the same exposure level. If your dog is on a grain-free, pea-heavy, or legume-heavy diet, it's worth discussing with your vet, and any signs of decreased energy, coughing, difficulty breathing, or collapse warrant an immediate vet visit regardless of diet.
Safe portion size
A tablespoon for small dogs, a couple of tablespoons for large dogs.
And while you're thinking about what's good for your dog, keeping on top of flea and parasite prevention is just as important as diet.
