Pet Safety / Compounds / Grapes / raisins

Is Grapes / raisins safe for dogs and cats?

High risk for pets

Idiosyncratic acute renal failure reported in dogs with no established dose-response; some dogs tolerate large quantities while others develop oliguria/anuria after a small amount. Mechanism unknown (tartaric acid hypothesis unconfirmed). Raisins are more concentrated and higher risk per gram than fresh grapes. Immediate decontamination and renal monitoring recommended.

Risk for dogs

High risk

Idiosyncratic acute renal failure reported in dogs with no established dose-response; some dogs tolerate large quantities while others develop oliguria/anuria after a small amount. Mechanism unknown (tartaric acid hypothesis unconfirmed). Raisins are more concentrated and higher risk per gram than fresh grapes. Immediate decontamination and renal monitoring recommended.

Risk for cats

Moderate risk

Acute renal failure cases in cats reported but far less frequently than in dogs; cats are less likely to consume grapes due to dietary preferences. Precautionary avoidance recommended given the severity of dog cases and idiosyncratic mechanism.

Regulatory consensus

1 regulatory bodyhas classified Grapes / raisins.

AgencyYearClassificationNotes
Unknown——

Regulators apply different standards of evidence — animal-data weighting, exposure-pattern assumptions, epidemiological power thresholds — which is why two scientific bodies can review the same data and reach different conclusions. The disagreement is the data.
