This tool estimates the potential toxicity of raisins ingested by your dog and provides risk assessments based on current veterinary guidelines.

Inputs

• Dog’s Body Weight: Enter your dog’s weight in kilograms (kg) or pounds (lbs).
• Number of Raisins Ingested: Approximate number of raisins your dog has eaten.

Outputs

• Total Raisin Intake (g)
• Raisin Dose per kg Body Weight (mg/kg)
• Toxicity Risk Level
• Recommended Action

Calculation Method

Raisin toxicity in dogs is highly individual, but studies suggest that doses as low as 2.8–3 g/kg body weight can be toxic or even lethal in some cases. Since raisins vary in size and toxicity potential, this calculator assumes 1 raisin ≈ 0.5g for standardization.

Raisin Dose (g/kg) = (Number of raisins × 0.5 g) ÷ Dog’s body weight (kg)

Toxicity Guidelines

• < 2.8 g/kg: Low risk – monitor closely.
• 2.8–11.6 g/kg: Moderate risk – contact your vet for advice.
• > 11.6 g/kg: High risk – immediate veterinary attention recommended.

Adverse Reactions

Dogs exposed to toxic amounts of raisins may exhibit symptoms such as:

• Vomiting (often within a few hours)
• Lethargy or weakness
• Diarrhea
• Abdominal pain
• Dehydration or reduced urination
• Kidney failure (can occur within 48–72 hours)

Risk Warning

Even small amounts of raisins can be dangerous for some dogs, and not all dogs show symptoms immediately. Toxicity is believed to be idiosyncratic, meaning some dogs may be more susceptible than others regardless of dose.

When to Contact Your Veterinarian

• If your dog ate any amount of raisins and you’re unsure of the quantity.
• If your dog shows signs of vomiting, lethargy, or abdominal pain.
• If raisin ingestion exceeds 1 g/kg body weight.
• Even if no symptoms appear, it is safest to consult your vet for early intervention such as inducing vomiting or administering activated charcoal.

Recommendation

If the dose exceeds the minimal risk threshold or if you’re unsure, it’s better to err on the side of caution. Prompt decontamination and fluid therapy can significantly reduce the risk of long-term harm. Do not wait for symptoms to appear—early veterinary care saves lives.
