Can dogs eat grapes? No. Grapes, raisins, currants, and sultanas can cause sudden kidney injury in dogs, and there is no reliably safe amount. If your dog ate even one grape or raisin, contact your veterinarian or animal poison control now rather than waiting for symptoms.
Call a vet or poison control now. Do not wait for symptoms.

FAQ
How much Grapes is dangerous?
Dangerous at ANY amount: sensitivity varies wildly and even a few have caused kidney failure.
Can I treat this at home?
This isn't a wait-and-see food. There's no reliably safe amount.
When should I call the vet?
Any amount, even if your dog seems completely fine.
Can dogs have grapes?
No. Individual sensitivity is unpredictable, and even a small exposure can be serious. Call a veterinarian or animal poison control with your dog's weight, the time, and the best amount estimate.
Are grapes bad for dogs if the dog seems normal?
Yes. A dog can look normal early in the exposure, so the absence of symptoms is not an all-clear. Early professional advice matters because kidney injury may develop later.
