Grapes are toxic to dogs. This applies to all forms: fresh grapes, raisins, currants, grape juice, wine, and any food containing grapes or raisins. Grape or raisin toxicosis can involve acute kidney injury, and timing varies by case.
What makes grape toxicity particularly dangerous is individual variation. Some dogs may show few early signs while others develop serious kidney injury. Because a reliable safe threshold is not available for an individual dog, the practical advice is: zero grapes and raisins.
Current veterinary toxicology sources identify tartaric acid as a likely toxic principle, but owners should not try to calculate safety at home. Call a veterinarian or poison-control service.
Raisins are dehydrated grapes. The same toxic compounds present in a larger amount of fresh grapes are concentrated into a tiny handful of raisins. Even a small raisin exposure can be concerning, especially for small dogs, and should be discussed with a veterinarian or poison-control service.
Raisins appear in many common foods: raisin bread, trail mix, granola bars, cookies, fruitcake, certain cereals, and salads. Be vigilant about these foods being accessible to dogs.
Signs may develop within hours, but timing varies. Watch for:
Do not wait for symptoms before calling your vet. By the time kidney failure symptoms appear, significant damage may have already occurred.
Call your veterinarian or ASPCA Animal Poison Control Center (888-426-4435) immediately. Note the approximate quantity consumed and when it happened. Follow your vet's instructions on whether to induce vomiting. If directed to an emergency vet, bring the product packaging if possible.
Treatment may include induced vomiting, activated charcoal, IV fluid therapy, kidney function monitoring, and in severe cases, dialysis. Early veterinary guidance matters because decontamination and kidney monitoring are time-sensitive.
Dogs can enjoy some fruits, but choose dog-appropriate portions and preparation. Options often used as treats include blueberries, seedless watermelon without rind, apple slices without seeds or core, strawberries, and small banana slices.
