My dog ate chocolate (unknown type) — what should I do?
Depends on the dose — check the calculator
What to do now
- Risk depends on how much theobromine your dog ate per kg of body weight (20 mg/kg → YELLOW, 40 mg/kg → RED). Use the PawPanic calculator with your dog's weight and the amount.
- If you can't estimate the amount, assume the worst and call your vet or a poison hotline.
- Remove any remaining material and keep packaging/labels — the vet will want product names and amounts.
- Do not induce vomiting unless a vet or poison-control expert tells you to.
- Note the time it was eaten, roughly how much, and your dog's weight.

Why it's a problem
Theobromine and caffeine (methylxanthines). Risk depends on type: darker chocolate has more. When the type is unknown, PawPanic uses the semisweet/dark estimate (~5.6 mg/g) from Merck — if it was baking chocolate or cocoa powder, use those pages instead (much higher).
Symptoms to watch for
Vomiting, diarrhea, thirst, restlessness, racing heart, tremors, seizures.
When: 6-12 hours; can last 72 h
⚠️ Prefer the milk / dark / baking / white / cocoa-powder pages when you know the type. Baking chocolate and cocoa powder are far more concentrated than this unknown-type estimate.
