Quick answer: no. Grapes, raisins, sultanas and currants can poison dogs and may cause acute kidney failure. The toxic amount is unpredictable: a dog can become seriously ill after a small exposure even if a previous exposure caused no obvious problem.
Last evidence check: 17 September 2026. Written by Super Dog Diets. General information only; this page cannot assess an individual poisoning.
What to do
- Remove access to the fruit or food containing it.
- Call your veterinary practice immediately.
- Keep the packaging or recipe and note the amount and time eaten.
- Do not wait for symptoms and do not induce vomiting unless instructed.
Remember that raisins, sultanas and currants may be hidden in fruit cake, hot-cross buns, mince pies, cereal, trail mix and chocolate products.
Possible signs
Vomiting, diarrhoea, abdominal pain, low energy and reduced appetite may occur. Kidney injury can develop later. Rapid assessment gives the veterinary team the best opportunity to reduce absorption and monitor kidney function.
