For the record, Chocolate poisoning is only rarely fatal to dogs.
Actually, we had this one beagle, named Mooky. I was young enough that I don't remember too many of his hijinks. Neither did I get to name him, which is why it's something lame like "mooky". In any case, this dog was a pound dog and an escape artist and all around trouble maker. One day he got into a full pound of chocolate truffles -and apparently got into other food, There was a hersey's kiss shaped pile of poo that weighed at least as much as he did. Left on my brother's bed.
