my daughter had a border collie eat a whole box of chocolate covered cherries, that dog had the Oklahoma quick step for three days. we had a Irish setter steal and eat a bag of Whoppers “malted milk balls” we had to evacuate the the house and make sure there were no open flames or pilot lights on. one of the most fowl odors i think i have ever smelled
