🍇 Fruit

Can dogs eat grapes?

Toxic — do not feed
No, grapes are toxic to dogs and can cause kidney failure.

Why

Grapes, raisins, and currants can cause acute kidney injury in dogs, and tartaric acid is the suspected toxic component. Toxicity is unpredictable: there is no established safe dose, and some dogs react to very small amounts regardless of breed, age, or size. Even a small ingestion warrants immediate veterinary attention.

Warning signs to watch for

Vomiting or diarrhea within 6 to 12 hours, followed by lethargy, loss of appetite, abdominal pain, weakness, dehydration, increased thirst, and potential kidney failure.
