My dog ripped into the trash and.....?

My dog ripped into the trash, and there was a old bag of molded raisin bagels in it. She ate all of the bagels which was probably about two in the bag. I'm scared for her because from what I'm told dogs aren't able to eat grapes or anything that has to do with them. I gave her a laxative prescribed by her vet, but I'm not sure that would even do anything besides make her use the bathroom. What else should I do? Please please help. My vet isn't in and he doesn't take house calls, especially at 1 in the morning.
