Can dogs eat raisins? No. Raisins, like grapes, can cause sudden kidney failure in dogs, and there's no known safe amount. Some dogs get sick after just a few, while others eat more and seem fine, so every raisin exposure should be treated as an emergency. If your dog ate raisins, call your vet or a pet poison control line now.
Toxic. Never feed raisins. That includes golden raisins, sultanas, currants and anything baked with them. If your dog ate any, call your vet right away, even if your dog seems fine. Early treatment gives the best chance of protecting the kidneys.

My Dog Ate Raisins: What to Do Right Now
Act fast. Call your vet, the ASPCA Animal Poison Control Center at (888) 426-4435 or the Pet Poison Helpline at (855) 764-7661 (fees may apply). Have your dog's weight, what was eaten, roughly how much and when. Don't make your dog vomit at home unless a vet tells you to. Vets often make the dog vomit if it was recent, then may give activated charcoal and IV fluids and check kidney values over the next few days.
Even if your dog ate only a few raisins and seems normal, call. Kidney damage can begin before you see any signs.
Why Are Raisins Toxic to Dogs?
For years the cause was a mystery. In 2021, toxicologists at the ASPCA Animal Poison Control Center identified tartaric acid as the likely culprit, as ASPCApro reports. Raisins are dried grapes, so the compound is concentrated, which is one reason raisins are often considered riskier per bite than fresh grapes. Dogs seem to be especially sensitive to it, and the amount varies between batches, which explains why reactions are so unpredictable. Our grapes guide covers grapes in more detail.
Signs of Raisin Poisoning
| Time after eating | Possible signs |
|---|---|
| Within about 6 to 24 hours | Vomiting, often with raisins in it; diarrhea; lethargy; loss of appetite |
| 24 to 48 hours | Belly pain, weakness, dehydration, increased thirst |
| 24 to 72 hours | Less urine or none at all, bad breath, signs of kidney failure |
Typical timeline described by veterinary sources such as VCA Animal Hospitals. Not every dog shows every sign.
A dog that stops producing urine is in serious danger and needs emergency care.
Where Raisins Hide
- Trail mix and granola
- Cereals and breakfast bars
- Oatmeal raisin cookies and muffins; see our oatmeal guide
- Raisin bread, hot cross buns and fruitcake; see our bread guide
- Salads, couscous and curries
- Chocolate-covered raisins (two toxins at once)
- Kids' snack boxes left in backpacks
How Many Raisins Are Toxic?
There's no amount known to be safe. Reported cases include dogs harmed by small amounts, while some dogs eat more without problems. Because no one can predict which dog will react, vets treat any raisin ingestion as potentially serious. Size matters too: a handful is far more dangerous for a Chihuahua than for a Great Dane, but large dogs are not immune.
Safe Snacks Instead
- Blueberries, fresh or frozen
- Apple slices, seeds and core removed
- Plain, fresh cranberries in small amounts
- Banana pieces
Dried cranberries are often mixed with raisins in snack packs, so check before sharing.
Keeping Raisins Away From Dogs
Store dried fruit and cereal in closed cupboards, ask kids not to share snacks, and tell guests and pet sitters that raisins and grapes are off limits. Check bread, cookies and holiday baking before offering any crumbs. Our toxic foods list is handy to print for the fridge.
Raisins vs Grapes: Is One Worse?
Raisins are simply dried grapes, so the same toxic compound is present. Because drying removes water, a handful of raisins packs much more fruit into a small space than a handful of grapes, and dogs tend to gulp them quickly. That's why many vets treat raisin exposures with extra caution. Sultanas, golden raisins and currants carry the same risk, and so do grape juice, grape jelly and wine-soaked baked goods. If it started as a grape, keep it away from your dog.
How soon should I call after my dog eats raisins? Right away. Treatment works best within the first few hours, before the kidneys are affected.
Why do some dogs eat raisins and seem fine? Sensitivity and the amount of the toxic compound vary. Since no one can predict who will react, every exposure needs a call to your vet.

Yes. Kidney damage can start before signs appear, and early treatment works best.
Are golden raisins and sultanas also toxic?
Yes. All raisins, sultanas and currants carry the same risk.
Are cooked raisins in baked goods safe?
No. Baking doesn't remove the risk.
