Grapes and raisins are highly toxic to dogs. Even small amounts can cause vomiting, diarrhea, lethargy, and acute kidney failure. The exact toxic substance is still being researched, but tartaric acid is suspected. All grape varieties (red, green, seedless, peeled) and grape products (raisins, currants, juice) are dangerous. If your dog eats grapes, contact your vet or poison control immediately.
