Nine Poisonous Foods Your Dog Should Never Eat

1. Chocolate

Chocolate can be lethal to dogs even in small doses due to the methylxanthines found in the cacao used to make it. Darker chocolate contains more of these substances and is more lethal than milk and white chocolates, but all three should be kept away from your dog. Methyxanthines, including caffeine, are toxic to dogs because they simply can’t digest or process these chemicals.
