My 25 kg dog ate a bowl of chicken stew that had two cooked grapes mixed in — is the cooked form

Short answer

No, cooking does not destroy the toxin. Grapes are dangerously unpredictable and can cause sudden kidney failure in dogs, and no safe amount is known. Two grapes could be enough to harm a dog his size, and being in a stew means he also ingested salt, fats, and onions which complicate things. Watch closely for vomiting, diarrhoea, or loss of appetite in the next 12-24 hours, which are early signs. Do not wait for more severe symptoms like reduced urination. Call your vet now to discuss whether he needs to be seen, based on his exact weight and the timing.

Toxic. Can cause sudden acute kidney failure in dogs — no safe amount is known. Raisins are equally dangerous.

Dogs and cats carry the same rating (Do not feed), so the notes below hold for either pet.

Grapes should not be given to dogs at all. Even a small amount can do harm, so there is no portion small enough to be safe.

Do not induce vomiting and do not give milk or oil to “dilute” it. Note the food and roughly how much was eaten, then call your vet or a pet poison hotline and follow their advice on whether to bring the pet in straight away.

Why these cautions matter

Grapes and raisins are linked to kidney failure in dogs, and no safe amount is reliable — some pets react after only a few.

Grapes has no place in everyday feeding: keep the rest of the day's food unchanged after this and watch the next walk and the stool that comes with it.
