About this calculator

This calculator estimates the risk of toxicity in dogs after ingesting grapes or raisins, based on the animal's weight and the amount ingested. Grapes are considered toxic from 32 grams per kilogram of body weight; raisins, from 11 g/kg. The tool compares the ingested dose with these thresholds to indicate potential risk.

How it works: enter the dog's weight in kg and the amount of grapes or raisins ingested in grams. The calculator divides the ingested amount by the weight to get the relative dose and compares it with the toxicity thresholds. The result shows if the dose is below, near, or above the limit, helping decide whether veterinary care is needed.

When to use: in accidental ingestion situations, such as when a dog eats grapes left on the table or raisins in treats. The calculator is useful for owners unsure if the amount ingested is dangerous. Remember: even small amounts can cause reactions in sensitive dogs; the tool is a guide, not a substitute for professional evaluation.

Cautions: grapes and raisins can cause acute kidney failure in dogs, even at low doses for some individuals. The calculator uses average thresholds, but sensitivity varies. If there is any suspicion, especially with symptoms like vomiting or lethargy, seek veterinary care immediately. Never induce vomiting without guidance.

Frequently asked questions

My dog ate one grape. Should I be worried?

Yes, any amount can be toxic. Use the calculator with the weight and amount to assess risk. If symptoms appear, see a vet.

What is the difference between grapes and raisins in toxicity?

Raisins are more concentrated: the toxic threshold is 11 g/kg versus 32 g/kg for grapes. So a smaller amount of raisins can be dangerous.

Does the calculator replace the vet?

No. It is a screening tool. When in doubt or if symptoms occur, always consult a veterinarian.

Can I give seedless grapes to my dog?

No. All parts of the grape are toxic to dogs, regardless of seeds or skin. Avoid giving grapes or raisins.

What if my dog ate grapes and is vomiting?

Vomiting is a sign of intoxication. Take him to the vet immediately. Do not try home treatment.
