My dog ate a huge tootsie roll, will she be okay?

She's a little chihuahua, and she must've pulled it off the table when I was at school. It's one of those big ones, which makes my situation worse. She's acting fine, nothing out of the ordinary, but i'm still worried about her. My cousin's chihuahua ate a whole bag of hershey's kisses and she was fine, does that mean mine will be too?
