If it eases anyone's mind at all, I've had a number of experiences personally (before all of the media attention about chocolate and dogs) and anecdotally with dogs consuming chocolate and never had any problems arise. My roommate had a wolf-hybrid (half wolf, half husky) who ate about a large quantity of fudge--stole it right off of the kitchen counter--and he laid around around for a bit, but was fine. Her mother had the same thing happen with their yellow lab. The dog stole everything if you turned your back for a second, including enough raw fish for 6 people. Again, no ill effects from the chocolate. I'm sure both had upset tummies, but wouldn't we all

.
My parents also used to give our dogs chocolate icecream when I was a kid. They were fine. Never had a problem. (I've also never had an issue with dogs or cats and lactose intolerance). Bottom line, I guess, is that some dogs have a food allergy or whathaveyou, but don't panic and think it's an automatic death sentence if your dog gets in the chocolate. I know people have a tendency to beat themselves up or feel they've been irresponsible and cruel. Your dog might be fine. Follow the proper steps but don't panic.
