1. What is Chocolate Toxicity?

Chocolate toxicity occurs when animals (especially dogs) ingest chocolate containing theobromine, a compound they metabolize more slowly than humans. The severity depends on the amount and type of chocolate consumed relative to the animal's weight.

2. How Does the Calculator Work?

The calculator uses the chocolate toxicity equation:

\[ Toxicity = \frac{(Chocolate\ Grams \times Theobromine\ mg/gram)}{Weight\ kg} \]

Where:

Typical Theobromine Content:

3. Toxicity Risk Levels

Mild toxicity: 20 mg/kg - vomiting, diarrhea
Moderate toxicity: 40 mg/kg - tachycardia, hypertension
Severe toxicity: 60 mg/kg - seizures, cardiac arrhythmias
Potentially lethal: 100-200 mg/kg

4. Using the Calculator

Instructions: Enter the amount of chocolate consumed (grams), select or enter the theobromine content (mg/gram), and the animal's weight (kg). The calculator will determine the theobromine dose in mg/kg.

5. Frequently Asked Questions (FAQ)

Q1: Which animals are most at risk?
A: Dogs are most susceptible due to slow theobromine metabolism. Cats are less likely to ingest chocolate but are also at risk.

Q2: How long does it take for symptoms to appear?
A: Symptoms typically appear within 6-12 hours after ingestion and can last up to 72 hours.

Q3: What should I do if my pet ate chocolate?
A: Contact your veterinarian immediately. Induce vomiting only if instructed by a professional.

Q4: Is white chocolate dangerous?
A: White chocolate contains minimal theobromine (0.25 mg/g) but the high fat/sugar content can cause pancreatitis.

Q5: How accurate is this calculator?
A: This provides an estimate. Individual sensitivity varies - always consult a veterinarian for actual cases.
