Made from spent cocoa beans used in the production of chocolate, cocoa
bean
mulch contains caffeine and theobromine, both of which are toxic to dogs.
Depending on the amount ingested, symptoms range from vomiting and
diarrhea
(as exhibited by a 50-pound dog who had eaten about two ounces
of the mulch) to tremors, seizures and death.

According to my vets, this also apparently applies to normal chocolate.

I understand that the chocolate sold specifically for dogs in pet shops has
had the nasties removed and is safe.
