Chocolate Types & Theobromine Content
Average theobromine concentrations found in different types of chocolate. The darker and more bitter the chocolate, the higher the toxicity risk.
| Chocolate Type | Theobromine (mg/g) | Theobromine (mg/oz) | Risk Profile |
|---|---|---|---|
| White Chocolate | 0.01 | ~0.25 | Negligible |
| Milk Chocolate | 1.50 | ~42.0 | Moderate |
| Dark Chocolate | 5.00 | ~140.0 | High |
| Semi-Sweet / Bittersweet | 5.80 | ~165.0 | High |
| Cocoa Powder | 8.00 | ~225.0 | Very High |
| Baker’s Chocolate / Nibs | 12.00 | ~340.0 | Extreme |
Dog Chocolate Toxicity FAQ
Learn more about theobromine poisoning, symptoms, and what to do in an emergency.
Chocolate contains substances called methylxanthines, specifically theobromine and caffeine. While humans can metabolize these easily, dogs process them much more slowly, allowing the toxins to build up to dangerous levels in their system and affect their heart, nervous system, and kidneys.
Toxicity is calculated based on three factors: your dog’s body weight, the amount of chocolate consumed, and the type of chocolate. Darker and more bitter chocolates contain significantly higher concentrations of theobromine. The calculator determines the milligrams of theobromine per kilogram of your dog’s body weight (mg/kg) to assess the risk level.
Symptoms typically appear within 6 to 12 hours and can include vomiting, diarrhea, excessive thirst, panting, restlessness, increased heart rate, muscle tremors, seizures, and in severe cases, cardiac failure or death.
If you suspect your dog has eaten a toxic amount of chocolate, contact your veterinarian, an emergency vet clinic, or a pet poison helpline immediately. Do not wait for symptoms to appear, and do not induce vomiting unless explicitly instructed to do so by a veterinary professional.
White chocolate contains only trace amounts of theobromine (about 0.25 mg per ounce), making theobromine poisoning highly unlikely. However, it is very high in fat and sugar, which can still cause severe stomach upset, pancreatitis, or obesity if consumed in large quantities.
