Overview

Grapes and raisins are extremely toxic to dogs and can cause acute kidney failure, even in small quantities. The exact toxic compound has not been identified, and there is no way to predict which dogs will react - some dogs eat grapes without apparent harm while others suffer kidney failure from just a few. Raisins are more concentrated and therefore more dangerous per piece. This also includes grape juice, wine, currants, and foods containing grape products like trail mix or certain baked goods. Any grape or raisin ingestion in a dog should be treated as a medical emergency.

Symptoms

Vomiting, lethargy, kidney failure, decreased urination

12-24 hours

What to do
