Why Is Chocolate Toxic to Dogs?
Chocolate contains theobromine (and caffeine), both of which dogs metabolize far more slowly than humans. Theobromine accumulates to toxic levels, causing vomiting, diarrhea, seizures, heart arrhythmia, and death. Darker chocolate has more theobromine — baking chocolate is the most dangerous.
Chocolate Theobromine Reference
| Type | Theobromine/oz | Risk Level |
|---|---|---|
| White chocolate | ~0.25 mg/oz | Very low (fat/sugar risk) |
| Milk chocolate | ~64 mg/oz | Moderate |
| Dark chocolate | ~393 mg/oz | High |
| Baking chocolate | ~450 mg/oz | Very high |
FAQs
How much chocolate is dangerous for a dog?
As a guideline: mild symptoms start at ~20 mg/kg theobromine; severe symptoms at 40-60 mg/kg; fatalities reported at 100+ mg/kg. For a 20 lb dog, just 1 oz of baking chocolate (~450 mg theobromine / 50 mg/kg) is a severe emergency.
Will my dog be okay after eating a little chocolate?
Maybe, but you should always call your vet. Some dogs are more sensitive than others. Early treatment (inducing vomiting within 2 hours, activated charcoal) is far more effective than waiting for symptoms.
