Can dogs eat grapes or raisins?

No — grapes and raisins are highly toxic to dogs and must never be given to them.

This is one of the most important pet safety facts every dog owner should know. Even a small amount of grapes or raisins can trigger acute kidney failure in dogs. The exact toxic compound has not been conclusively identified, which means there is no "safe" dose — any quantity should be treated as a potential emergency.

All forms are dangerous

Raisins are simply dried grapes and are actually more concentrated in toxins per gram. Also avoid:
- Grape juice and grape-based products
- Raisins hidden in bread, cereal, or trail mix
- Wine and grape jam

Why the risk is unpredictable

Some dogs have eaten grapes and shown no reaction, while others have developed life-threatening kidney failure after eating just a few. Individual sensitivity varies and cannot be predicted, so the only safe approach is zero exposure.

Signs of grape toxicity (appear within 6–12 hours)

- Vomiting and diarrhoea (often containing grape pieces)
- Lethargy and weakness
- Loss of appetite
- Abdominal pain
- Decreased or absent urination (a sign of kidney failure)
- Tremors in severe cases

Treatment

Prompt veterinary intervention — including induced vomiting, activated charcoal, and IV fluids to support kidney function — dramatically improves the outcome. Time is critical.
