Poisonous to Dogs and Cats: Unsafe Food List

My dog is about 35 lbs and she got into a 1/2 lb of fudge, I immeditely gave her activated charcoal, she had thrown up a bit already, she was walking around and whining, I took her for a walk but she was not able to urinate. I also gave her magnesium capsules and then a bunch of water. She kept vomiting, which I thought was good.
