Dog Raisin Toxicity Calculator
Assess the risk when a dog eats grapes or raisins. No safe dose is known — any amount can be toxic.
Formula
Dose = (amount × type multiplier) ÷ body weight (kg)
- No safe threshold for grapes/raisins in dogs has been established.
- Raisins are ~4.5× more concentrated than fresh grapes.
- Toxicity can cause acute kidney failure. Symptoms: vomiting, lethargy, anuria.
20 lb dog eats 5 g raisins

- Amount Eaten: 5 g
5 g raisins ≈ 22.5 g grape equivalent. 20 lbs = 9.07 kg. 22.5 ÷ 9.07 ≈ 2.5 g/kg → HIGH risk.
