What This Calculator Does

This tool estimates the amount of theobromine your dog may have consumed based on their weight, the type of chocolate, and the amount eaten.

It then categorises the risk from low to emergency, helping you decide how urgently your dog may need veterinary care.

What Your Result Means

The result reflects the estimated dose of theobromine in milligrams per kilogram of body weight.

Higher doses are more likely to cause clinical signs such as vomiting, agitation, tremors, and seizures.

This calculator provides guidance only. Dogs vary in sensitivity, and symptoms can develop over time.

Important

This tool is designed to support decision making but does not replace veterinary advice.

If your dog is unwell, showing symptoms, or you are unsure, contact a veterinarian immediately.
