Quick answer: No — grapes and raisins are toxic to dogs and can cause sudden kidney failure, even in tiny amounts.
Grapes seem harmless, but they’re one of the most serious everyday hazards for dogs — and there is no known “safe” amount.
Why grapes (and raisins) are dangerous
Grapes, raisins, currants and sultanas can cause sudden, acute kidney failure in dogs. The exact toxic compound still isn’t fully understood, and sensitivity varies wildly — some dogs react to a single grape — so the only safe rule is none at all.
Signs to watch for
Vomiting (often within hours), lethargy, loss of appetite, and decreased or absent urination as kidney damage sets in.
What to do
Treat any grape or raisin ingestion as an emergency. Call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately — early treatment is critical.
Safe fruit alternatives
Stick to dog-safe fruits like blueberries, apple slices (cored), watermelon (seedless) and strawberries.
