Raisin & Grape Toxicity FAQ
Critical information about this life-threatening emergency for dog owners.
Yes, raisins (and grapes) are highly toxic to dogs and can cause acute kidney failure, which can be fatal. There is no known safe dose; even a small amount can be dangerous for some dogs [[1]].
The most common early symptom is vomiting, typically appearing within 6–12 hours of ingestion. Other signs include diarrhea, lethargy, loss of appetite, and abdominal pain [[2]].
This is a medical emergency. Contact your veterinarian or the nearest emergency animal hospital immediately. Do not wait for symptoms to appear. Early treatment, which may include inducing vomiting and IV fluids, is critical to prevent kidney damage [[32]].
The calculator uses established veterinary toxicology data. The toxic threshold for raisins is approximately 2.8 grams per kilogram of a dog’s body weight. It calculates the percentage of this toxic dose your dog has consumed to provide a risk assessment.
Yes, many dogs can survive with prompt and aggressive veterinary care. The prognosis is much better when treatment begins before kidney damage occurs. This is why immediate action is so crucial [[5]].
