Chocolate Toxicity Calculator : How much chocolate can kill a dog?

Chocolate and dogs

A dog’s body can’t handle the high levels of caffeine and theobromine in chocolate, which are toxic to dogs. The quantity of chocolate an average-sized dog needs to ingest before it has a bad reaction varies from dog to dog and type to type of chocolate.

Chocolate is poisonous to dogs as it contains theobromine. Humans easily metabolize theobromine, but dogs process it much more slowly, allowing it to build up to toxic levels in their system. The potential toxicity of chocolate to your dog depends on the type of chocolate, the amount consumed and your dog’s size. In large enough amounts, chocolate and cocoa products can kill your dog.
