The full answer
Grapes and dried grape products — raisins, sultanas and currants — are on standard veterinary toxin lists. Ingestion has been linked to acute kidney injury in dogs.
Reactions appear to vary a great deal between individual dogs, and no reliably safe quantity has been established. That is exactly why the standard advice is not to feed them at all and to call a vet after any ingestion.
Is Grapes Good for Dogs?
There is no benefit that justifies the risk. Any nutrient in grapes is available from foods that are not associated with kidney injury in dogs.
Risks and Things to Know
- Associated with acute kidney injury, which can be life-threatening
- Sensitivity varies widely between dogs — small amounts have caused problems in some cases
- Raisins, sultanas and currants are concentrated and appear in many baked goods
- Hidden sources include fruit cake, trail mix, cereal bars, hot cross buns and mince pies
How Much Can Dogs Eat?
There is no recommended amount. Grapes and dried grapes should not be fed to dogs in any quantity.
Keep grapes, raisins and baked goods containing them well out of reach, including in bags and lunchboxes.
How Should I Prepare It?
- None — this food should not be prepared for dogs.
- Check ingredient lists of baked goods and snack bars before sharing anything with your dog.
