Can dogs eat chocolate? What happens if they do? Dogs cannot eat chocolate because the methylxanthine derivatives in chocolate can be a relatively serious health hazard to dogs. Although chocolate has similar hazards for humans, humans can metabolize these substances, while dogs cannot, so once you eat chocolate outside of your dog’s tolerance, your dog may die suddenly. The ability of dogs to eat chocolate is also related to size and the amount of chocolate consumed. Generally speaking, the bigger the dog is the less chocolate will affect it. So if a large dog accidentally eats a small amount of chocolate the owner does not need to panic, but if it is a small dog, 120 grams of chocolate can cause fatal danger.
