Can Dogs Eat Grapes?
Short answer: No. Grapes and raisins are toxic to dogs and can cause sudden kidney failure, even in small amounts. Call your vet or an animal poison hotline right away if your dog ate any.
Why it’s a problem
Grapes, raisins, sultanas and currants can cause acute kidney injury in dogs. The exact toxic substance is still being studied, and the amount that causes problems varies a lot between dogs, so there is no known safe dose.
How much and how to serve it
None. Don’t offer grapes or raisins as treats, and keep raisin bread, trail mix, cereal and baked goods that contain them out of reach.
Risks to watch for
- Early signs can include vomiting, diarrhea, lethargy and loss of appetite.
- Kidney damage can follow, with reduced urination and abdominal pain, sometimes within a day or two.
- Raisins, currants and sultanas carry the same risk as fresh grapes.
What to do if your dog ate grapes
Treat it as an emergency even if your dog seems fine. Call your vet or an emergency clinic, or the ASPCA Animal Poison Control Center at (888) 426-4435, and tell them your dog’s weight and roughly how much was eaten and when. Don’t try to make your dog vomit unless a veterinarian tells you to. Early treatment gives the best chance of avoiding kidney damage.
