Can Dogs Eat Raisins?
4-minute read · Loyal Saints Food Safety Library
Quick answer
No — raisins are toxic to dogs and can cause sudden kidney failure, even in small amounts. As dried grapes, they carry the same danger and are often hidden in cookies, trail mix, cereal, and baked goods. Never feed raisins. If ingested, contact your vet immediately.
Raisins — along with currants and sultanas — are dried grapes, and they carry the same serious toxicity: they can cause acute kidney failure in dogs, sometimes from small amounts. The toxic mechanism isn't fully understood, and sensitivity varies unpredictably between dogs, so there's no known safe amount.
Raisins are especially risky because they're so often hidden in everyday foods: oatmeal raisin cookies, trail mix, granola, cereal, scones, and certain breads. Many accidental poisonings happen when a dog eats a baked good. Symptoms include vomiting, lethargy, decreased appetite, and reduced urination (a sign of kidney damage). If your dog eats raisins, contact your veterinarian or animal poison control immediately — prompt treatment is critical.
