Dog Grape & Raisin Toxicity Calculator
Calculate toxicity exposure for dogs that consumed grapes, raisins, sultanas, or currants. Tartaric acid poisoning emergency assessment.
Grape & Raisin Exposure Estimator
Grapes and raisins contain Tartaric Acid which can cause acute kidney failure in sensitive dogs. Inducing vomiting within 2 hours is strongly advised by toxicologists.
How to Use the Dog Grape & Raisin Toxicity Calculator
- Enter dog weight in lbs or kg.
- Select fruit type (Fresh Grapes, Seedless Raisins, Sultanas, Zante Currants).
- Enter quantity consumed (number of individual grapes/raisins or total weight in grams/oz).
- Get instant toxicity exposure alert and emergency decontamination protocol.
Clinical Methodology & Formula Breakdown
Research has identified Tartaric Acid / Potassium Bitartrate as the toxic agent in grapes/raisins, causing acute renal tubular necrosis. Because individual sensitivity varies, ANY ingestion is treated as an emergency.

Worked Clinical Example
Grape & Raisin Exposure Comparison
| Fruit Type | Relative Toxicity | Lowest Documented Toxic Dose |
|---|---|---|
| Fresh Grapes | Baseline High Hazard | ~0.7 oz / kg (~4-5 grapes for a small dog) |
| Seedless Raisins | 4.5x Concentration Hazard | ~0.11 oz / kg (~10-12 raisins for a medium dog) |
| Sultanas / Currants | Extremely High Hazard | ~0.10 oz / kg |
| Grape Juice / Wine | Severe Toxic Hazard | Any non-zero volume containing grape extract |
Frequently Asked Questions
Why are grapes and raisins toxic to dogs?
In 2021, veterinary toxicologists identified Tartaric Acid as the toxin. Tartaric acid causes acute damage to the proximal renal tubules in canine kidneys.
Can a dog eat just one grape safely?
No dose of grapes or raisins is considered safe. Sensitivity varies unpredictably between individual dogs.
What are early signs of grape poisoning?
Vomiting within 2-6 hours, loss of appetite, lethargy, abdominal pain, diarrhea, and decreased urine production (anuria).
How quickly does kidney failure occur after grape ingestion?
Acute renal failure develops within 24 to 72 hours following ingestion.
What treatment will the vet perform for grape toxicity?
Induction of vomiting, activated charcoal administration to bind toxins, and 48 hours of aggressive IV fluid therapy to protect kidney function.
