Research
-
Chocolate contains cocoa beans. These beans contain theobromine and caffeine.
-
Theobromine is a natural occurring compound found in the cacao plant. It is a white or colourless solid.
-
Dark chocolate, baking chocolate, and unsweetened chocolate are more toxic than any other chocolates because the theobromine and caffeine levels are higher than any other type of chocolate.
-
White chocolate is the safest type of chocolate because the theobromine and caffeine levels are the lowest.

Conclusion
If your dog eats a large amount of dark chocolate, baking chocolate, and unsweetened chocolate it is highly likely that your dog will have a severe reaction. Dogs are more at risk for severe toxicity if their weight is on the smaller side.
Get professional help right away. Call your vet and bring your animal in to your nearest clinic! They have ways of not allowing the theobromine to be absorbed into your dog's system.
So don’t worry if your dog eats chocolate because now you know what to do when it happens!
