A Hershey bar weighs 1.55 ounces, so let's say all of the is chocolate (I'm assuming you're talking about a milk chocolate Hershey bar). If she ate one and a half of them, that would be between 2 and 3 ounces of chocolate. According to my chocolate toxicity calculator, she should be OK with this dose. You might see some mild GI upset, such as vomiting and diarrhea. I would withhold food for several hours to see how she does, and take her to the vet if you see any stomach upset. I have seen one or two dogs who were exceptionally sensitive to even small amounts of chocolate, although this is rare. If you want to be completely safe you are within a good window of time to take her to your vet's and have vomiting induced.
