Raisins are toxic to pets. Even small amounts may trigger acute kidney injury. The toxic dose is unpredictable and no safe threshold has been established. Contact a veterinarian or poison service promptly for any suspected ingestion.
Raisins are dried grapes sold plain or mixed into cereals, trail mixes, baked goods, and snack bars. Drying concentrates sugars and the compounds linked to grape toxicity.
Common sources include raisin bread, oatmeal cookies, granola bars, stuffing mixes, and fruit-and-nut blends. Labels may show raisins, sultanas, golden raisins, currants, or raisin paste.
Raisins are smaller and denser than fresh grapes, so several may be eaten quickly. Lunchbox leftovers, trail-mix pieces, and bakery crumbs are common household exposure points.
