Dog Chocolate Toxicity Calculator
Calculate theobromine and caffeine toxicity levels to assess chocolate poisoning risk in dogs
Calculate Chocolate Toxicity Risk
Enter your dog's current weight
Select the type of chocolate consumed
Estimate the total amount of chocolate consumed
Example: 20kg Dog Ate 50g Milk Chocolate
Theobromine dose: (2.4 mg/g × 50g) ÷ 20kg = 6.0 mg/kg
Caffeine dose: (0.85 mg/g × 50g) ÷ 20kg = 2.1 mg/kg
Total dose: 6.0 + 2.1 = 8.1 mg/kg
Assessment: Safe level (<15 mg/kg) - Monitor for symptoms

Understanding Chocolate Toxicity in Dogs
Why is Chocolate Toxic to Dogs?
Chocolate contains methylxanthines (theobromine and caffeine) that dogs metabolize much more slowly than humans. While humans can process these compounds quickly, dogs' bodies take 17-20 hours to eliminate half the ingested amount, leading to toxic buildup.
Calculation Method
- •Theobromine dose: (chocolate content × amount) ÷ dog weight
- •Caffeine dose: (chocolate content × amount) ÷ dog weight
- •Total dose: Sum of both methylxanthines in mg/kg
Toxicity Formula
Total Dose = (Theobromine + Caffeine) × Amount ÷ Weight
- Safe Level: <15 mg/kg total methylxanthines
- Factors: Dog size, chocolate type, amount consumed
- Onset: Symptoms appear 6-12 hours after ingestion
- Duration: Effects can last 12-36 hours
Prevention & Treatment
Prevention is key - keep all chocolate products away from dogs. If ingestion occurs, early intervention can prevent serious complications. Treatment may include induced vomiting, activated charcoal, IV fluids, and supportive care.
Remember: This calculator provides estimates only. Always consult your veterinarian for professional medical advice if chocolate ingestion is suspected.
