The Complete Guide to Dogs Eating Peas: Bad for The Heart?

This content was reviewed and fact-checked by veterinarian Dr. Aukse Caraite, DVM.

Yes, dogs can eat peas in moderation, and these small green veggies can offer some nutritional benefits. However, before adding peas to your pup’s diet, there are a few important factors to consider. While fresh or frozen peas without added salt or seasoning are generally safe, some forms, such as canned peas, often contain excess sodium, which can be harmful to dogs. Plus, what about pea pods or split peas? Can certain types of peas cause digestive issues or allergies? Are peas in grain-free dog food linked to dilated cardiomyopathy (DCM)? This guide will explore the benefits, potential risks, and the safest way to incorporate peas into your dog’s diet.

Are Peas Good For Dogs?

Peas can be a healthy and nutritious dog treat when given in moderation.

Always feed peas in moderation. Avoid canned peas with added sodium or preservatives. Plain, fresh, or frozen peas are the safest options; however, pea pods should be offered only if they are soft and digestible.

Risks & Considerations Before Feeding Peas to Dogs

While peas can be a healthy and nutritious treat for dogs when given in moderation, there are several risks and considerations to keep in mind before feeding them to your canine companion:

Are Peas Linked to Dilated Cardiomyopathy (DCM) in Dogs?

Current research on the link between peas, legumes, and grain-free diets and dilated cardiomyopathy (DCM) in dogs reveals a complex and evolving landscape. While early studies suggested a strong association, newer research presents conflicting evidence, and the exact mechanism remains unclear.

Below is a synthesis of key findings from recent studies:

Study Focus	Findings	Year
Biochemical profiling of diets	Peas linked to cardiac-metabolism disruptions	2021
20-week pulse diet trial	No DCM in Huskies fed high-pulse diets	2023
Cardiac troponin I levels	Elevated in dogs eating pea/lentil/potato diets	2021
4-week pea vs. lentil diet	Pea diet caused DCM-like changes; lentil diet did not	2023

Sources: [1],[2],[3],[4]

Not all legumes, such as peas, and grain-free diets are linked to diet-related dilated cardiomyopathy (DCM) in dogs, and not every dog with DCM has consumed grain-free pet food. DCM is one of the most common heart diseases in dogs, so a dog diagnosed with DCM that has been eating a boutique, exotic, or grain-free (BEG) diet may not have developed the condition because of its food at all.

FDA stance: The FDA continues investigating but has not confirmed causality. Their last update (2022) states that no “meaningful new information” is available yet.

Practical guidance: While peas are strongly associated with these diet-related changes, the precise mechanisms and long-term risks require further study. Owners should be cautious with pea-heavy, grain-free diets until more is known.

Can Dogs Eat Peas Raw or Cooked?

Dogs can eat both raw and cooked peas, but cooked peas are generally easier to digest. Raw peas retain more nutrients but may cause gas in some dogs. If cooking, steam or lightly boil the peas without salt, oil, or seasonings. Avoid canned peas due to high sodium levels unless labeled as low-sodium and free from additives.

Are Dogs Allergic to Peas?

Risks

The following symptoms may indicate a bad reaction to peas.

What to Do If A Dog Reacts Badly to Peas

Dogs showing worsening symptoms, such as blood in their vomit or stool, difficulty breathing, weakness, or collapse, should be taken to the veterinarian immediately.

1. Contact a veterinarian immediately: Even if your dog seems fine, contact your veterinarian or an emergency pet poison hotline right away. This includes services such as the ASPCA Animal Poison Control Center at 1-888-426-4435 or the Pet Poison Helpline at 1-855-764-7661. If you can’t reach your vet, you can chat live with a registered online veterinary professional via our online vet chat or video chat support (24 hours a day, 7 days a week). You can also schedule an at-home veterinary appointment with The Vets, a mobile veterinary service that provides at-home vet care nationwide for just about everything.

2. Gather important information: When speaking to a vet, provide: Quantity consumed (estimate if unsure), time of ingestion, and dog’s weight and breed (to assess potential risk).

3. Follow veterinary instructions: The vet may suggest monitoring at home or emergency treatment at the clinic.

• Keep your dog calm and prevent them from eating anything else.
• Be prepared to transport your dog to the vet quickly if advised.
• Bring any remaining peas or packaging to help the vet assess the situation.

How to Safely Feed Peas to Dogs

When feeding peas to your dog, it’s important to follow a few simple guidelines to keep them safe:

Ways to Feed Peas to Dogs

As with any new food, it is recommended to start slowly and feed gradually to give the digestive system time to adjust.

How Much Peas Can Dogs Eat?

Treats should only constitute 10% of your dog’s diet, with the remaining 90% coming from well-balanced dog food. This guideline also applies to healthy treats like peas. Below, you’ll find general guidelines for safely portioning peas based on your dog’s weight.

Dog Size	Serving Size (Feed Occasionally)	Breed Examples
Extra-small (2-15 lbs.)	1–2 tsp peas (about 5–10 whole peas)	Shih Tzu, Yorkies, Chihuahuas, Maltese
Small (16-25 lbs.)	2–3 tsp peas (about 10–20 whole peas)	Boston Terriers, Beagles, Dachshunds
Medium (26-60 lbs.)	1–2 tbsp peas	Bulldogs, Basset Hounds, Border Collies
Large (61-90 lbs.)	2–3 tbsp peas	Golden Retrievers, Pit Bulls, Boxers, Labrador Retrievers
Extra-large (91+ lbs.)	¼ cup peas	Bullmastiffs, Great Danes, Saint Bernards, Great Pyrenees

Can Puppies Eat Peas?

Yes, puppies can eat peas, but only in moderation and very small amounts. Since puppies have more sensitive digestive systems, it’s best to start with just a few plain peas—about a teaspoon’s worth—to see how they react. Feeding too many peas at once can lead to digestive upset, as puppies’ stomachs are still developing and may have trouble handling the fiber. Fresh or frozen peas (thawed and unseasoned) are the safest option. Avoid canned peas, as they often contain added sodium or preservatives that can be harmful to puppies. Never feed peas cooked with onions, garlic, butter, or other seasonings, as these are toxic or hard to digest. When introducing peas or any new food, avoid offering multiple new items on the same day so you can monitor for any food sensitivities or allergic reactions. If your puppy experiences digestive issues, introducing one new food at a time makes it easier to identify the cause. Try offering a teaspoon of plain, soft peas—either mashed or whole—and then wait a few days to observe how your puppy’s digestive system reacts before offering more.

Alternatives
