Can Dogs Eat Raisins?
✗ Toxic : Dangerous
Concentrated grape toxins. Even small amounts dangerous.
Raisins are extremely toxic to dogs and must be strictly avoided. Raisins contain the same unidentified nephrotoxic compound as grapes but in a more concentrated form, making them exponentially more dangerous. Even a single raisin can trigger acute kidney failure in susceptible individuals. Symptoms appear within 24-72 hours and include vomiting, diarrhoea, lethargy, loss of appetite, and abdominal pain. There is no antidote, only supportive veterinary care. Raisin toxicity can be fatal. All dried fruits (sultanas, currants) carry the same risk.
Why Raisins Is Dangerous
Raisins contain the same unknown toxin as grapes but in a much more concentrated form. A single raisin or a small piece of fruit cake containing raisins has caused kidney failure in dogs. Particularly dangerous in Christmas and Easter foods.
What To Do If Your Dog Eats Raisins
Emergency vet visit required. Even one raisin warrants a call to your vet or your national animal poison helpline.

Watch out: Owners assume raisins are safe because they are simply dried grapes and do not realise the concentration effect. Raisins in cereals, baked goods, or trail mix are fed without checking ingredients. Some owners do not realise all dried grape products are equally toxic.
