Theobromine Content by Chocolate Type
| Chocolate Type | Theobromine (mg/oz) | Risk Level (50 lb dog, 3 oz) |
|---|---|---|
| White Chocolate | ~0.25 | Very Low |
| Milk Chocolate | ~44 | Low-Moderate |
| Semi-Sweet Chips | ~170 | Moderate |
| Dark Chocolate (60-70%) | ~210 | High |
| Dark Chocolate (85%+) | ~300 | High |

Toxicity Thresholds: Mild signs at 20 mg/kg · Severe at 40 mg/kg · Seizures at 60 mg/kg. The darker and more concentrated the chocolate, the more dangerous it is — a small amount of baking chocolate can be far more toxic than a large milk chocolate bar.
