So, we all think chocolate is awesome, right? That’s possibly because of a couple of compounds found in it: Theobromine and Caffeine.
They are both vasodilators. This means that they widen your blood vessels, stimulate your heart to beat faster, they are both diuretics (they make you pee more), and generally stimulate the nervous system.
This means that when we humans eat chocolate, we feel pumped up. Chocolate makes us feel good.
You and I have natural methods of processing both of these compounds. However, Fido’s natural processes do not work near as quickly as ours do to remove these compounds from his blood stream. Instead, these compounds ravage your dog’s natural regulatory systems. They just sit there in the blood, acting on the organs for far longer than is healthy.
If your dog has eaten enough to become ill, your dog will begin to show symptoms within 6-12 hours of consuming the chocolate. If you are looking for specific symptoms of what happens if your dog eats chocolate, please read our article here.
Primarily though, the Theobromine will begin to interfere with your dog’s heartbeat, potentially causing irregularities in his heart rate. In other words, the chocolate can cause your dog’s heart to go haywire. Depending on the amounts consumed, your dog may lose control of his limbs, suffer a seizure, and even fall into a coma. At the most extreme levels (which may not take all that much chocolate), your dog can even die.
