Grapes, raisins, sultanas, and even currants (some currants are actually small, black grapes) are toxic to your dog! There have also been anecdotal reports of cats and ferrets being affected. Ingestion of even a small amount of grapes, raisins, or currants can result in severe, acute kidney failure. Most, if not all, products that contain grapes or raisins may cause toxicity – this includes grape juice, trail mix with raisins, raisin bread, and possibly even wine. Additionally, some cookies and bars (including protein and snack bars) may contain raisin paste and some breads contain raisin juice. All grapes and raisins, seeded and seedless, organic and conventionally grown, can cause toxicity. The exact way these foods cause toxicity is still unknown and toxicity does not necessarily appear to be dose-dependent.  This unknown toxin can cause vomiting, diarrhea, abdominal pain, anorexia, and acute renal (kidney) failure.
