Can dogs eat grapes & raisins?
No — grapes and raisins can cause sudden kidney failure in dogs, even in small amounts.

🐱 Can cats eat this? →Why
In 2021, veterinarians at the ASPCA's poison-control centre identified tartaric acid as the likely toxic component. Dogs poorly excrete tartaric acid, so it can damage the kidneys — and because the amount varies wildly between grapes, there is no reliably 'safe' quantity.
How much matters
As a precaution, more than one grape or raisin per ~4.5 kg (10 lb) of body weight is treated as a potential emergency. Kidney injury can appear within 72 hours.
Signs of trouble to watch for
- Vomiting (often within hours)
- Lethargy & loss of appetite
- Increased or decreased thirst/urination
- Signs of kidney failure
