My 10 kg dog ate green beans cooked in a garlic and onion stew — should I induce vomiting?

Dogs · Food safety

Short answer

The green beans themselves are safe, but the garlic and onion in the stew are the real problem. That much allium is enough to damage red blood cells in a 10 kg dog, potentially causing anaemia. Signs like weakness, pale gums, and red-tinged urine may take a few days to appear. Do not induce vomiting unless your vet specifically instructs you to over the phone. The priority is to figure out how much stew he ate. Offer him plenty of fresh water and call your own vet, describing the approximate amount of the garlic-onion mixture he consumed.

Green beans — Food safety facts

Safe to share · Dogs · full breakdown on the linked food page

Safe, plain (no salt, garlic or onions added). A common diet-filler treat.

Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.

Green beans is not toxic to dogs. The real limit is calories, fat and salt, so treat it as a small extra alongside the normal ration rather than a meal in itself.

There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.

Why these cautions matter

Garlic and onion damage a pet's red blood cells and can bring on anaemia. Signs are often delayed for several days, so looking fine straight afterwards does not rule it out.

A heavy salt load drives up thirst and urination, and in the worst cases leads to sodium ion poisoning, which is a genuine emergency.

Green beans can stay on the rotation, but only as an extra mouthful: keep the rest of the day's food unchanged and watch the next walk and the stool that comes with it.
