Short answer

No. Grapes, raisins, sultanas and currants are toxic to dogs. Pet Poison Helpline says eating them can cause vomiting, belly pain or diarrhea, followed quickly by kidney injury and kidney failure. The ASPCA also lists grapes and raisins as foods to keep away from pets. Call a vet or a pet poison hotline if your dog eats any.

What the sources say

Pet Poison Helpline lists common grapes, muscadines, raisins, sultanas and Zante or Corinthian currants as toxic for dogs. ^[1]

Poisoning starts with stomach and gut upset such as vomiting, belly pain and diarrhea, and is followed rapidly by kidney injury and kidney failure. ^[2]

Tartaric acid in grapes and raisins is the suspected toxin, but this has not been proven. Most reported poisonings are in dogs. ^[2]

Grapes and raisins also appear on the ASPCA's list of foods pets should not have, because of the risk to the kidneys. ^[3]

FAQ

What if my dog only ate one or two?

Call anyway. Pet Poison Helpline notes that many factors, including the amount eaten and the size of the dog, decide what is toxic for a pet, so let an expert judge.

Are cats at risk too?

Pet Poison Helpline says poisoning is mainly reported in dogs, but it refers to companion animals in general, so keep grapes and raisins away from all pets.
