Are grapes and raisins poisonous to dogs and cats?
Can cause sudden kidney failure in dogs. There is no known safe amount.
Call your vet or the Animal PoisonLine straight away, even if your pet seems fine. Many poisons don't cause signs for hours, and treatment works best early. Keep the packet or a photo of what they ate. Don't try to make them sick unless a vet tells you to.
Why it's a problem
Grapes, raisins, sultanas and currants can cause kidney failure in dogs. Some dogs are affected by a handful and others are not, and there is no way to tell in advance. Cooked versions, like in hot cross buns, Christmas cake and mince pies, are just as dangerous. Cats may be affected too.
Signs to look out for
- Being sick, often within a few hours
- Diarrhoea
- Being quiet, weak or off their food
- Peeing less, or not at all, a day or more later
Getting help
Call your own vet first. If they're closed, their phone line will tell you who covers out of hours. The Animal PoisonLine (01202 509 000, a charge applies) gives 24-hour advice to owners.
