The Short Answer
No. Chocolate is genuinely toxic to dogs — call your vet immediately if your dog ate any.
Why Chocolate Is Dangerous
Chocolate contains theobromine, which dogs metabolize ~5x slower than humans. Even small amounts can be fatal in small breeds.
Theobromine and caffeine are both methylxanthines. Dogs lack the liver enzymes to clear them quickly, so they accumulate to toxic levels in the bloodstream. Dark chocolate and baker's chocolate are the most dangerous — milk chocolate is less concentrated but still dangerous in large amounts.
Toxic Threshold
Roughly 20 mg theobromine per kg of body weight is mildly toxic; 40-50 mg/kg causes serious cardiac symptoms; 60+ mg/kg can be fatal. That means even one square of dark chocolate is dangerous for a 15 lb Dachshund.
Symptoms to Watch For
- Vomiting

- Restlessness or hyperactivity
- Rapid heart rate
- Tremors or seizures

When to Call the Vet
Always. Even if symptoms haven't started yet. The earlier you induce vomiting (within 2 hours of ingestion), the better the outcome. Call ASPCA Animal Poison Control at (888) 426-4435 — there's a fee but they'll tell your vet exactly what to do.
