Chocolate Poisoning in Dogs 🐕

Yes, chocolate is toxic to dogs. While rarely fatal, chocolate ingestion can result in significant illness. Chocolate is toxic because it contains a chemical called theobromine, as well as caffeine. Theobromine is the main toxin in chocolate and is very similar to caffeine. Both chemicals are used medicinally as a diuretic, heart stimulant, blood vessel dilator, and a smooth muscle relaxant. Dogs cannot metabolize theobromine and caffeine as well as people can. That is why dogs are more sensitive to the chemicals’ effects. 

The amount of toxic theobromine varies with the type of chocolate. The darker and more bitter the chocolate, the more dangerous it is to dogs. Baking chocolate and gourmet dark chocolate are highly concentrated and contain 130-450 mg of theobromine per ounce.
