1. What is Chocolate Toxicity in Dogs?

Chocolate contains theobromine and caffeine, which are toxic to dogs. Dark chocolate is particularly dangerous as it contains higher concentrations of these substances. The toxicity depends on the amount consumed relative to the dog's weight.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• 200 mg/oz — The approximate theobromine content in dark chocolate
• Chocolate Amount — Ounces of dark chocolate consumed
• Weight — Dog's weight in kilograms

Explanation: The formula calculates the approximate theobromine dose in mg per kg of body weight, which determines the toxicity level.

3. Understanding the Results

Risk Levels:

• ≥100 mg/kg: Severe risk - Potentially fatal, emergency care needed
• 60-99 mg/kg: High risk - Serious symptoms likely, contact vet immediately
• 20-59 mg/kg: Moderate risk - May cause vomiting, diarrhea, restlessness
• <20 mg/kg: Low risk - Mild or no symptoms expected

4. Using the Calculator

Tips: Enter the amount of dark chocolate consumed in ounces and the dog's weight in kilograms. For milk chocolate, use about 60 mg/oz instead of 200 mg/oz.

Q4: Are some dogs more sensitive?
