  As I recall, Good & Plenty is a licorice candy, right?  Licorice on it's own is not toxic, however, he may experience some diarrhea.  I don't know if there is any artifical sweetner in this candy, if so that could be a problem as it can be toxic.  If it were me, I would call my vet's office when they open and ask them.  Otherwise just watch him.  |
