Can dogs eat raisins?
No — raisins are highly toxic to dogs and can cause sudden, fatal kidney failure. Because they're a concentrated form of grapes, even a few raisins are more dangerous than a few grapes.

Frequently Asked Questions
- There is no safe amount. Documented cases show acute kidney failure in dogs after eating as few as 3-5 raisins (in dogs weighing 22-44 lbs). Smaller dogs are at even higher risk. Because raisins are dehydrated grapes, the toxic compounds are concentrated — making them more dangerous than the same number of fresh grapes. If your dog ate even one raisin, contact your veterinarian or ASPCA Animal Poison Control (888-426-4435) immediately. Don't wait for symptoms.
- Early symptoms appear within 6-24 hours and include vomiting, diarrhea, loss of appetite, lethargy, and abdominal pain. As kidney damage progresses (24-72 hours), you'll see decreased urination or no urination at all, increased thirst, foul breath, and weakness. By the time these later signs appear, kidney damage may be irreversible. The earlier treatment starts — ideally within hours of ingestion — the better the outcome. Even if your dog seems fine after eating raisins, get to the vet immediately.
- Treat any raisin-containing food as toxic. Raisin bread, oatmeal raisin cookies, fruitcake, granola bars, raisin bran, hot cross buns, scones, and trail mix all contain enough raisins to cause harm. The other ingredients (sugar, butter, sometimes chocolate or xylitol) make matters worse. If your dog steals a raisin-containing food, count it as a raisin ingestion and call your vet immediately. Read labels carefully when sharing any baked goods, and assume 'fruit-flavored' or 'mixed dried fruit' contains raisins or grapes unless proven otherwise.
