Can Dogs Eat Grapes & Raisins?
Emergency🚨 Dangerous — act now
No — grapes and raisins can cause sudden kidney failure in dogs, and there is no established safe amount. Even a few can be an emergency for some dogs.
Grape and raisin toxicity is one of the scariest poisonings in dogs because it's unpredictable: some dogs eat several with no effect while others develop acute kidney failure from a small handful. Research points to tartaric acid as the likely culprit, and concentration varies by fruit — which explains the randomness. Because there's no way to know if your dog is sensitive, every ingestion is treated as an emergency.
What makes it dangerous: Tartaric acid (suspected)
Symptoms to watch for
- Vomiting within hours
- Lethargy and weakness
- Loss of appetite
- Drinking/urinating more, then less
- Kidney failure within 24–72h
What to do right now
- Take this seriously even for one or two grapes — sensitivity is unpredictable
- Call your vet or a pet poison hotline immediately
- If ingestion was recent, your vet may induce vomiting — time matters
- Watch for vomiting or lethargy over the next 24 hours even if advised to monitor
