Raisins (and grapes) can cause sudden kidney failure in dogs, even in tiny amounts.
Dried grapes are even more concentrated than fresh, so the same toxic dose comes in a much smaller volume. There is no established safe amount.
The toxic agent is believed to be tartaric acid and potassium bitartrate, which dogs cannot metabolize. Sensitivity varies dramatically between individuals — some dogs tolerate small amounts while others develop acute kidney injury from a single raisin. Damage targets the proximal tubular epithelium of the kidneys within 24–72 hours.

Toxicity has been documented at doses as low as 0.7 g/kg for raisins. A single raisin can cause illness in a small dog. Treat any ingestion as a veterinary emergency.
Contacte de inmediato con su veterinario o con una línea de emergencia de intoxicaciones para animales. No provoque el vómito a menos que se lo indique un veterinario.
