Why Chocolate Is Toxic to Dogs?
Chocolate contains two chemical compounds, theobromine and, to a lesser extent, caffeine. Both of which can speed up your dog’s heart rate and stimulates their nervous system. Humans can quickly metabolize them, but dogs can not, making it more dangerous for dogs. In addition, dogs cannot process caffeine and theobromine quickly, which allows these toxic chemicals to build up in their systems and cause poisonous signs associated with chocolate toxicity.
In general, it is believed that dark chocolate and cocoa powder have the greatest toxicity due to their higher levels of methylxanthines, caffeine being one of these. Chocolate in its various forms can be potentially fatal to a dog if ingested in large enough quantities. After ingestion, clinical signs of poisoning tend towards vomiting and diarrhea but may include hyperactivity or excitability, elevated body temperature, and heart rate, seizures, panting, abnormal heart rhythms (arrhythmia), blood in urine or stool.
