For what it's worth, some years back one of my dogs ate an entire package of D-con, including most of the box (she was a good sized dog, probably about 70 lbs). We spotted the remains of the box, saw that she was looking VERY green, and rushed her to the emergency vet (of COURSE this happened on a Sunday!). They induced vomiting (I think), kept her overnight, and she was fine after a bit. All of which really has no relevance to the original question, but I thought I'd throw it out there just for information purposes.
