Moderate risk — toxic dose around 1 oz per lb of body weight
Dark chocolate
High risk — toxic dose around 0.3 oz per lb of body weight
Cocoa powder/baking chocolate
Very high risk — the most concentrated source of theobromine

| Treatment Item | Estimated Cost |
|---|---|

How to Prevent This
The best treatment is prevention. Keep your pet safe with these steps.
