Why dogs can’t eat chocolate?
Chocolate is toxic to dogs because it contains chemicals called methylxanthines, specifically theobromine. Theobromine is the main toxin in chocolate and is very similar to caffeine.
Just a little bit of chocolate can cause diarrhea and vomiting in dogs, while too much can cause seizures, irregular heart function and even death.
Are you suggesting we provide chocolate to dogs in we wanted to induce diarrhea and vomiting in dogs?
Chocolate should never be used to induce diarrhea and vomiting in dogs.  If your dog has ingested something it should not have done it is important you talk to your local vet as soon as possible. Do not try to treat it yourself.
