Can Dogs Eat Green Beans? Yes

Why it’s safe

Green beans are a popular dog-friendly vegetable. They are low in calories and provide fiber and vitamins A, C and K, plus minerals such as potassium and magnesium, so they make a light treat or topper. AKC notes their fiber and bulk may help some dogs feel full while adding few calories.

The things to avoid are in the preparation. AKC advises avoiding canned green beans because of their high salt content, and seasoned or restaurant green beans may be cooked with butter, garlic or onion, none of which suit dogs. Green bean casserole is not safe because it typically contains sugar, salt, fat, onion and garlic. Plain fresh or cooked beans are better. PetMD recommends removing stems and strings and cutting beans into bite-size pieces, and it warns that frozen beans can be a choking or blockage hazard.

Green beans can be part of a veterinarian-supervised weight-management plan, but PetMD cautions that the online "green bean diet" is not a valid weight-loss plan, and they should never replace complete dog food. Too many can cause gas, diarrhea or vomiting, so build up gradually.

Benefits

Low in calories, useful as a light treat
Source of fiber, vitamins A, C and K, and minerals
Crunchy and satisfying for many dogs
Cheap and easy to prepare

Risks

Canned beans often contain added salt
Seasonings, butter, onion or garlic make them unsuitable
Frozen or long pieces can be a choking or blockage hazard
Too many can cause gas, diarrhea or vomiting

How to serve it safely

Rinse fresh green beans, trim the ends, remove any strings, and cut them into bite-size pieces. Serve raw or steamed or boiled with nothing added, and let cooked beans cool. If you use canned beans, choose no-salt-added and rinse them well.

Treats should stay under 10% of daily calories, and PetMD gives smaller portions for smaller dogs. Start with a few pieces and increase slowly. If your dog is on a prescribed diet or a weight-loss plan, ask your vet how to include them, as swapping food by volume needs to be planned.

If your dog already ate it

A few green beans, even a large number, are unlikely to be serious. Expect possible gas or loose stools and offer water.

Call your vet if your dog ate green beans prepared with onion, garlic, butter, or large amounts of salt, or if your dog is choking, retching, vomiting repeatedly, has a painful belly or stops eating. For possible toxic seasonings, you can call ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 (US; fees may apply), or your local emergency vet. Do not try to make your dog vomit at home.

Frequently asked questions

Can dogs eat raw green beans?

Yes. Raw green beans are safe for most dogs, cut into bite-size pieces. Cooking makes them easier to digest.

Are green beans good for overweight dogs?

They are low in calories and can add bulk to a meal, but they are not a diet on their own. Ask your vet before changing a weight-loss diet.

Can puppies eat green beans?

In small, soft, cut-up pieces, yes. Puppies have sensitive stomachs, and too much fiber can upset them, and they still need complete puppy food as their main diet.

Can dogs eat canned green beans?

Only if they are no-salt-added and rinsed. Standard canned beans have added salt.
