Dog Raisin Toxicity Risk Calculator
Dog Raisin Toxicity Risk Calculator
Raisins (and other Vitis fruits such as grapes and currants) can cause serious poisoning in dogs, including acute kidney injury. Sensitivity varies widely between dogs, so even small exposures should be treated seriously. Use this calculator to estimate the dose relative to body weight and to understand urgency based on time since ingestion.
How the calculator estimates exposure
The primary metric is dose per body weight:
\( \text{Dose}_{g/kg} = \frac{m_g}{W_{kg}} \)
Where \(m_g\) is the total mass of raisins eaten in grams and \(W_{kg}\) is the dog’s weight in kilograms.
For users who prefer imperial units, the calculator also shows:
\( \text{Dose}_{oz/lb} = \frac{m_{oz}}{W_{lb}} \)
Risk level and why it is conservative
There is no reliably defined safe dose for raisins and grapes in dogs, and outcomes can vary from no symptoms to severe kidney failure. Because of this uncertainty, the risk level in this tool is intentionally conservative and always recommends contacting a veterinarian or pet poison control.
Why time since ingestion matters
Early veterinary care can meaningfully improve outcomes. Time since ingestion is used to display urgency because rapid decontamination and supportive care may be most effective when started early. Clinical signs such as vomiting or diarrhea may appear hours after ingestion, but kidney injury can develop later, so waiting for symptoms is not a safe strategy.
What to do if your dog ate raisins
- Call a veterinarian or pet poison control immediately with your dog’s weight, estimated amount eaten, and the time since ingestion.
- Do not induce vomiting at home unless specifically instructed by a veterinary professional.
- Monitor closely for vomiting, diarrhea, lethargy, decreased appetite, or reduced urination, and seek urgent care if any signs appear.
Important limitations
This calculator provides screening guidance, not a diagnosis or treatment plan. If you are unsure about the amount eaten, use your best estimate and still seek professional advice. When in doubt, treat the situation as urgent.
