What Makes Chocolate Toxic to Dogs

Chocolate contains a chemical compound called theobromine, which is toxic to dogs. While humans can metabolize theobromine easily, dogs process it much more slowly, which can lead to a buildup of the chemical in their systems.

Theobromine can cause a range of symptoms in dogs, from vomiting and diarrhea to seizures, heart failure, and even death.

How Much Chocolate Is Too Much?

  • White chocolate: While white chocolate contains very little theobromine, it is still high in fat and can cause digestive upset if consumed in large amounts.
  • Milk chocolate: Milk chocolate contains around 60-90 mg of theobromine per ounce. While small amounts are unlikely to cause harm, ingestion of larger amounts can lead to symptoms such as vomiting, diarrhea, and restlessness.
  • Dark chocolate: Dark chocolate contains around 150-250 mg of theobromine per ounce. Ingestion of just a few ounces of dark chocolate can be fatal to a small dog.
  • Baker’s chocolate: Baker’s chocolate is the most toxic of all, containing up to 450 mg of theobromine per ounce. Even a small amount can be fatal to a small dog.
