Dog Raisin Toxicity Calculator
Dog Raisin Toxicity Calculator
The Dog Raisin Toxicity calculator helps determine potential toxicity risk when a dog consumes grapes or raisins. Enter your dog’s weight in pounds or kilograms. Input number of grapes or raisins consumed, or their weight in grams.
Select whether the consumption was grapes or raisins.
A typical raisin weighs about 0.5-1.5 grams. A small box (1.5 oz) contains about 40-45 raisins. A cup of raisins is approximately 145-165 grams.
- Dog’s Weight: 10 kg
- Raisins Consumed: 30 g
Toxic Dose = 2.8 g/kg
Toxicity Risk Level = (30 / 2.8) 10 = 107.14 g
*Result: High risk. Immediate veterinary attention is required.

How to Calculate how many grapes are toxic to dogs?
Determine your dog’s weight in kilograms or pounds. Estimate the number of raisins consumed. Multiply number of raisins by ~1 gram (average raisin weight). Divide the total raisin weight by your dog’s weight in kg.
For grapes, multiply the count by 5 grams (average grape weight).
For raisins, multiply the count by 0.5 grams (average raisin weight). Calculate the consumption ratio by dividing the total grams consumed by your dog’s weight in kilograms. Compare this ratio to risk levels: above 3 g/kg indicates severe risk, above 1 g/kg indicates high risk, and any amount is concerning.
- Dog’s Weight: 5 kg
- Raisins Consumed: 10 g
Toxicity Risk Level = (10 / 2.8) 5 = 17.86 g
*Result: Moderate risk. Consult a vet.
- Dog’s Weight: 20 kg
- Raisins Consumed: 40 g
Toxicity Risk Level = (40 / 2.8) 20 = 285.71 g
*Result: Severe risk. Seek emergency veterinary care immediately.
Toxicity Formula
Grams per Kg = Total Grams Consumed ÷ Dog's Weight in Kg
Where:
Total Grams = Number of Grapes × 5g (for grapes)
Total Grams = Number of Raisins × 0.5g (for raisins)
Risk Levels:
Severe Risk: ≥ 3 g/kg
High Risk: ≥ 1 g/kg
Concerning: Any amount
The formula requires:
- Dog’s Weight: Weight in pounds or kilograms
- Amount Consumed: Number or weight of grapes/raisins
- Type: Grapes or raisins
- Time: Hours since consumption
Small Dog Example
- Dog’s Weight: 10 lbs (4.54 kg)
- Consumed: 3 grapes
- Calculation: (3 × 5g) ÷ 4.54 kg = 3.30 g/kg
- Result: Severe Risk – Emergency veterinary care needed
Medium Dog Example
- Dog’s Weight: 30 lbs (13.61 kg)
- Consumed: 10 raisins
- Calculation: (10 × 0.5g) ÷ 13.61 kg = 0.37 g/kg
- Result: Concerning Risk – Veterinary consultation needed
Large Dog Example
- Dog’s Weight: 70 lbs (31.75 kg)
- Consumed: 20 grapes
- Calculation: (20 × 5g) ÷ 31.75 kg = 3.15 g/kg
- Result: Severe Risk – Emergency veterinary care needed
Puppy Example
- Dog’s Weight: 5 lbs (2.27 kg)
- Consumed: 2 raisins
- Calculation: (2 × 0.5g) ÷ 2.27 kg = 0.44 g/kg
- Result: Concerning Risk – Veterinary consultation needed
Critical Example
- Dog’s Weight: 15 lbs (6.80 kg)
- Consumed: 25 grapes
- Calculation: (25 × 5g) ÷ 6.80 kg = 18.38 g/kg
- Result: Severe Risk – Immediate emergency care required
What is Dog Raisin Toxicity?
Dog Raisin Toxicity refers to the potentially fatal reaction dogs can have to consuming grapes or raisins. The exact toxic compound remains unknown, and sensitivity varies between individual dogs. Even small amounts can cause severe kidney damage or failure. Symptoms typically appear within 24 hours and may include vomiting, diarrhea, lethargy, and decreased urination.
