Chocolate is toxic to dogs because it contains methylxanthines (theobromine and caffeine). Signs of chocolate toxicity typically appear within 2 to 12 hours after your dog has eaten chocolate. Knowing the level of theobromine ingested and the size of the dog is key.
Use our dog chocolate toxicity calculator to figure out whether your dog has eaten a potentially toxic amount.
