What Should I Do if My Dog Ate Chocolate?
If you think your dog has eaten chocolate, or if they have any of these symptoms, contact the Pet Poison Helpline at 855-764-7661 or your veterinarian or emergency vet right away:
- Increased body temperature
- Increased reflex responses
- Muscle rigidity
- Rapid breathing
- Increased heart rate
- Low blood pressure
- Advanced signs (cardiac failure, weakness, and coma)
Keep in mind, with any poisoning, it’s always cheaper, less invasive, and has a better prognosis/outcome if you treat early. If your dog has already developed clinical signs associated with chocolate toxicity, the veterinarian visit may be more expensive, and the outcome may be worse.

What Makes Chocolate Toxic to Dogs?
Chocolate contains substances known as methylxanthines (specifically caffeine and theobromine), which dogs are far more sensitive to than people. Different types of chocolate contain varying amounts of methylxanthines. In general, though, the darker and more bitter the chocolate the greater the danger.
For instance, a 50-pound dog could become equally sick from eating 8 ounces (½ pound) of milk chocolate as they would from 1 ounce of baker’s chocolate. This is because the darker chocolate is more toxic, so a smaller amount would still result in toxicity.
Why Isn't Chocolate Toxic to Humans?
Humans can break down and excrete methylxanthines such as theobromine much more efficiently than dogs.
