Can dogs eat grapes?
No. Grapes, raisins, and currants can cause acute kidney failure in dogs, and the danger is uniquely unpredictable: some dogs eat several and are fine, others suffer kidney injury from a small amount, and no safe dose has ever been established. Size of the dog does not reliably protect it. For years the toxin was a mystery; in 2021, ASPCA poison control veterinarians identified tartaric acid, concentrated in grapes, as the likely culprit, which also explained cases involving cream of tartar and homemade playdough.
If your dog just ate grapes or raisins, this is a call-now situation: your vet or the ASPCA Animal Poison Control Center at 888-426-4435. Early treatment, often inducing vomiting and IV fluids, is highly effective; waiting for symptoms, vomiting, lethargy, changes in urination, means damage may already be underway.
Add to the same never list: chocolate, xylitol (in sugar-free gum and some peanut butters), onions, garlic, and macadamia nuts.
No, never: grapes and raisins can cause kidney failure in dogs, with no safe established dose. If your dog ate some, call the vet or the ASPCA poison line now, not tomorrow.
