🔴 Call your vet or a poison line now
Grapes and raisins (including currants, and foods that contain them like trail mix or baked goods) can cause acute kidney failure in dogs. The toxic dose is unpredictable — some dogs react to very small amounts, and there is no way to know in advance. Don't wait for symptoms. The sooner a vet acts (often by inducing vomiting), the better the outcome.
