Most dog owners know chocolate can harm their pets, but why? And how much is dangerous? As veterinary experts explain, here's what you need to know.
Cacao contains theobromine, a bitter alkaloid that humans metabolize easily, gaining benefits like reduced blood pressure, better focus, and improved mood. Dogs, however, process it slowly. In excess, it speeds up heart rate, damages kidneys, and overstimulates the nervous system in our four-legged friends.
Not all dogs react the same. Toxicity depends on the amount ingested and the dog's weight.
Mild symptoms like vomiting, diarrhea, and restlessness appear at 20 mg of theobromine per kg of body weight. Heart issues arise at 40-50 mg/kg, and seizures at over 60 mg/kg.
Symptoms typically emerge 6-12 hours after ingestion and can persist up to 72 hours.
Darker chocolates with higher cocoa content are riskiest, packing more theobromine. For instance, 70% dark chocolate has about 802 mg/kg, while a Twix has around 40 mg/kg.
For clarity, the Bionica site offers a simple toxicity calculator. Input your dog's weight, chocolate type (white, milk, or dark), and amount consumed.

If your dog eats a concerning amount, contact your vet immediately. They'll assess based on size, chocolate type, and quantity—advising monitoring or a clinic visit.
If needed, vets may induce vomiting or administer activated charcoal to bind toxins before absorption into the bloodstream.
