Chocolate exposure logic
A dog chocolate calculator estimates exposure by combining chocolate type, amount eaten and dog weight. The key entity is theobromine, one of the methylxanthines in chocolate. Dark chocolate and baking chocolate generally create higher exposure per gram than milk chocolate.
Dose-style formula
Dose estimate = estimated substance amount / body weight. For pet tools, body weight needs to be current and in the unit the calculator expects, such as kg or lb.
Dog food planning
Food estimates often use daily energy need divided by food energy density. If a food has 3.6 kcal per gram and the target is 720 kcal per day, the estimate is 200 g per day before treats and veterinary adjustments.
Urgent caveats
- A calculator cannot diagnose poisoning.
- Unknown amounts should be treated conservatively.
- Symptoms, age, breed, health status and time since ingestion matter.
- A veterinarian or poison helpline needs to guide suspected toxic exposure.

FAQ
Can a calculator decide whether my dog needs treatment?
No. It can only screen inputs. A veterinarian or poison helpline needs to guide suspected toxic exposure.
Why does chocolate type matter?
Dark and baking chocolate generally contain more methylxanthines per gram than milk chocolate, so the same weight can mean higher exposure.
