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
Concentrated grape toxins. Even small amounts dangerous.
What To Do If Your Dog Eats Raisins
This is a veterinary emergency. Call your vet or the Animal Poison Line (01202 509000) immediately. Note how much your dog ate and when.
Use the Emergency Risk ToolCommon Mistakes
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.
Frequently Asked Questions
Why are raisins so dangerous if one nut seems small?
Raisins concentrate the nephrotoxic compound from fresh grapes; even one can cause kidney failure.
How quickly does raisin poisoning appear?
Symptoms appear within 24-72 hours: vomiting, diarrhoea, lethargy, and loss of appetite.
Is there a treatment for raisin poisoning?
No antidote exists. Only supportive veterinary care and monitoring can help.
Are sultanas and currants equally dangerous?
Yes, all dried grape products carry identical toxicity risks.
Can dogs recover from raisin poisoning?
Some recover with aggressive supportive care, but kidney damage may be permanent; many cases are fatal.
