Chocolate Toxicity Calculator for Dogs
Determine if your dog has consumed a potentially dangerous amount of chocolate and what symptoms to expect based on the type and quantity of chocolate ingested.
How to Use This Calculator
- Enter your dog's weight in pounds
- Enter the amount of chocolate consumed in ounces
- Select the type of chocolate consumed
- Optionally, select when the chocolate was consumed
- Click Calculate Risk to see the potential toxicity level and recommended actions
Formula Used
Theobromine Dose (mg/kg) = (Chocolate Amount × Theobromine Content) ÷ Dog Weight
Where:
- Chocolate Amount = Amount consumed in ounces
- Theobromine Content = Varies by chocolate type (mg/oz): White (0.25), Milk (60), Semi-Sweet (150), Dark (450), Baker's (450), Cocoa (800)
- Dog Weight = Dog's weight in pounds (converted to kg for calculation)
Example Calculation
Real-World Scenario:
A 25-pound dog has eaten 4 ounces of milk chocolate. Let's determine the risk level.
Given:
- Dog Weight = 25 pounds (11.34 kg)
- Chocolate Amount = 4 ounces
- Chocolate Type = Milk Chocolate (60 mg theobromine per ounce)
Calculation:
Theobromine consumed = 4 oz × 60 mg/oz = 240 mg
Dose per kg = 240 mg ÷ 11.34 kg = 21.16 mg/kg
Result: This falls in the mild toxicity range (20-40 mg/kg), so the dog may experience mild symptoms like vomiting and diarrhea, but is unlikely to have severe complications.

Accuracy Notice
This calculator provides estimates based on average theobromine content for different chocolate types. Individual products may vary in their theobromine content. Individual dog sensitivity to theobromine can also vary based on age, health status, and other factors. This calculator should not be used as the sole basis for medical decisions.
