Dog Chocolate Toxicity Calculator
Use this dog chocolate toxicity calculator to assess the potential danger when a dog ingests chocolate.
For instance, if a 20-pound dog eats 3 ounces of milk chocolate, the calculator would indicate a mild risk of toxicity. But, if the same dog consumes 3 ounces of dark chocolate, the risk would be significantly higher due to the increased concentration of theobromine, the compound toxic to dogs.

Dog Weight (lbs) | Milk Chocolate (oz) | Dark Chocolate (oz) | Baking Chocolate (oz) |
---|---|---|---|
10 | 5 | 2 | 0.5 |
20 | 10 | 4 | 1 |
30 | 15 | 6 | 1.5 |
40 | 20 | 8 | 2 |
50 | 25 | 10 | 2.5 |

Dog Chocolate Toxicity Calculation Formula
The formula for calculating chocolate toxicity in dogs is based on the amount of theobromine and caffeine consumed per kilogram of body weight.
Toxicity = (mg of theobromine + mg of caffeine) / (dog's weight in kg)
For example, if a 10 kg (22 lb) dog eats 100 grams of milk chocolate:
Milk chocolate contains about 60 mg of theobromine per ounce (28.35 grams).
100 grams of milk chocolate contains: (100 / 28.35) × 60 = 211.6 mg of theobromine.
Toxicity = 211.6 / 10 = 21.16 mg/kg.
A dose of 20 mg/kg is considered mild toxicity, so this dog would likely experience mild symptoms.
How Much Chocolate Will Kill a Dog?
As a general rule:
- Mild toxicity occurs at about 20 mg of theobromine per kg of body weight.
- Severe toxicity occurs at about 40-50 mg/kg.
- Seizures can occur at 60 mg/kg.
- Potentially lethal doses start at 100-200 mg/kg.
When a 30-pound (13.6 kg) dog could experience severe toxicity from eating about 6 ounces of dark chocolate or 2 ounces of baking chocolate. It would take about 20 ounces of milk chocolate to reach the same level of toxicity.
The amount of chocolate that can be lethal to a dog varies based on the dog’s size and the type of chocolate. Dark chocolate and baking chocolate are more dangerous than milk chocolate due to higher theobromine content.
