What this tool does
Estimate grape or raisin exposure per kilogram — with the standing advice that any amount means call your vet. Published case-report lowest reported toxic doses (grapes ≈0.7 oz/kg, raisins ≈0.11 oz/kg). No safe dose has been established — current veterinary guidance is that any ingestion warrants a call to a veterinarian.
How to use the Dog Grape Toxicity Checker
- Enter or select dog weight in lb.
- Enter or select grapes or raisins eaten (grams).
- Enter or select what was eaten.
- Read the calculated result; change any measurement to compare alternatives.
Formula
estimated exposure (g/kg) = grams eaten ÷ dog weight in kg, compared with the lowest doses reported toxic in published case reports (grapes ≈19.8 g/kg, raisins ≈3.1 g/kg)

Frequently asked questions
There is no established safe number. Published case reports put the lowest toxic doses at roughly 0.7 oz of grapes per kg of body weight (about 19.8 g/kg) and 0.11 oz/kg for raisins — but individual dogs have reacted below tidy thresholds, so vets advise calling for any amount.
Raisins are dried grapes: the water is gone but the toxic compounds remain, so gram for gram a raisin dose equals several times its weight in fresh grapes. That is why the raisin threshold is about one-sixth of the grape figure.
No — call anyway. Grape toxicity is unpredictable and kidney damage is silent at first; symptoms (vomiting, lethargy, loss of appetite, reduced urination) can take a day or more. Early decontamination is simple; late kidney failure is not.
Artificially flavoured products without real grape are not the same risk, but real grape juice and wine contain the fruit. If a product contains actual grapes or raisins in any form, treat it as an ingestion and call.
No specific antidote exists. Treatment is prompt decontamination plus aggressive IV fluids and kidney monitoring for at least 48 hours — another reason the first call should happen immediately, not after symptoms.
