Chocolate contains methylxanthines (mainly theobromine and caffeine) that dogs metabolize slowly. Darker and baking chocolates generally carry higher risk per ounce than milk chocolate; white chocolate has much less theobromine but is still not a healthy treat. Related: toxic levels and symptom detail.
If your dog ate chocolate, call a veterinarian or pet poison hotline with the type, amount, and dog's weight. Do not wait for severe signs.
Key takeaways
- Risk depends on chocolate type, amount eaten, and the dog's size.
- Early signs can include vomiting, diarrhea, restlessness, panting, and increased thirst.
- Serious signs include rapid heart rate, tremors, seizures, and collapse.
- Baking chocolate, cocoa powder, and dark chocolate are usually more dangerous than the same weight of milk chocolate.
- Home treatment without veterinary guidance is unsafe.
