Ok, I cooked brownies and crumbs dropped on the floor. Harlem ate a very small crumb. It's been 4 days and he has runny stools and goes about 6 times a day. I feel sorry for him and was will never give him anything chocolate again ever. Any suggestions on how to calm his diarrhea or do you think it will pass? i thought by now, it would just pass from his system but it's just about 2:30pm today and he has pooped about 4 times since 9am.
