Formula
Total Theobromine (mg) = Chocolate (g) × mg/g for type
Dose (mg/kg) = Total Theobromine ÷ Weight (kg)
Mild symptoms may begin near 20 mg/kg; severe cardiac or neurological signs typically appear above 60 mg/kg. Thresholds vary between individual dogs.
Full Description
Chocolate contains methylxanthines (theobromine and caffeine) that dogs metabolize slowly, leading to toxicity. Darker chocolates carry higher concentrations, making even small amounts risky for small dogs.
Immediate veterinary care is crucial for moderate or severe exposures. Vets may induce vomiting, administer activated charcoal, and provide supportive care such as IV fluids and cardiac monitoring.
Frequently Asked Questions
Is white chocolate dangerous?
White chocolate contains minimal theobromine but can cause GI upset due to fat and sugar. Monitor and consult your vet if symptoms appear.
What if I do not know the chocolate type?
Use the most conservative estimate (baking chocolate). Veterinarians prefer to err on the side of caution.
How quickly do symptoms appear?
Signs typically begin within 2–4 hours but can be delayed. Seek help as soon as ingestion is suspected.
Can small amounts be given as treats?
No. Even small quantities can pose a risk, especially for small breeds. Offer dog-safe treats instead.
