Yes — safe in moderation
Yes — plain green beans are one of the best low-calorie treats for dogs, and vets often recommend them for dogs that need to lose weight. Raw, steamed or boiled, all fine.
Green beans are full of fibre and vitamins while being very low in calories, which makes them a brilliant filler for hungry dogs on a diet — the “green bean diet” of swapping some kibble for green beans is a well-known vet trick (done under guidance). They can be served raw, steamed or boiled, chopped to a safe size. The only things to skip are canned green beans with added salt and any cooked with butter, oil, onion or garlic.
A small handful of plain green beans for a medium dog is a healthy daily treat. Cut them down for small dogs to avoid gulping. Choose fresh or frozen, or no-salt canned. As with any new food, start with a little.
