How Much Chocolate Is Lethal to Dogs?
The lethal dose of theobromine for dogs is approximately 100-200 mg/kg. However, severe, life-threatening symptoms can occur at much lower doses (60 mg/kg). The type of chocolate matters enormously — baking chocolate is over 6x more concentrated in theobromine than milk chocolate.
Theobromine Concentrations by Chocolate Type
| Type | Theobromine/oz | Danger Level |
|---|---|---|
| White chocolate | ~0.25 mg/oz | Negligible |
| Milk chocolate | ~64 mg/oz | Moderate |
| Dark chocolate | ~150 mg/oz | High |
| Baking chocolate | ~390 mg/oz | Extremely high |
FAQs
Can one chocolate chip kill a dog?
A single chocolate chip contains roughly 0.2 oz of chocolate with about 13 mg of theobromine. For a large dog, this is negligible. For a very small dog (under 5 lbs), even a small amount of dark chocolate can cause symptoms. Always call your vet to be safe.
What if my dog ate a whole chocolate bar?
Use the calculator above to assess the risk level based on the bar type and your dog’s weight. Then call your vet or the Pet Poison Helpline (1-855-764-7661) immediately regardless of the calculated risk level.
