My dog ate about a cup and a half of semi sweet chocolate and she went to the vet and she was fine. Now at home though, for three nights, she has had diarrhea all night. Why is this and when will it stop?

The chocolate has provoked some ''gastrointestinal upset/inflammation'' which may be the primary cause of it. Sometimes secondary bacterial infection can prolong the signs for few days. I would suggest to start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice more diarrhoea, vomiting, lethargy or inappetence. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
