Toxicity to pets
Chocolate contains chemicals called methylxanthines, specifically theobromine and caffeine. Overdose of these chemicals results in gastrointestinal distress (e.g., vomiting, diarrhea), cardiovascular disorder (e.g., elevated heartrate, high blood pressure) and neurological signs (e.g., hyperactivity, tremor, seizure). The severity of the poisoning depends upon the amount and type of chocolate ingested and the size and health status of the patient. Be aware that chocolate candy and baked goods may also contain other poisonous foods including macadamia nuts, raisins, or xylitol (a sugar substitute).
To help estimate your dog’s specific exposure based on the type and amount of chocolate consumed and your dog’s weight, you can use our Chocolate Toxicity Calculator. It’s a helpful starting point, but always contact Pet Poison Helpline at (855) 764-7661 for a professional assessment.
