If your dog does have an issue with the chocolate, it will likely be within a few hours of eating it. Will you be able to watch her? If this were my dog, I most certainly would be giving her the hydrogen peroxide. Much better safe than sorry.
I have a friend whose dog died last year due to eating dark chocolates. RIP River Girl

"...1. Feed the dog a nice big bowl of food so it has some extra 'stuff' to throw up. In the case of pills this makes it more probable that that all of the pills will come up. In the case of other nasty stuff, it gives the dog more volume to help things come up easier (important when you need to get bones or plastic to come up)
2. Use a medicine dropper - sold at any pharmacy for giving kids medicine - to give the dog 1 tablespoon of hydrogen peroxide. Three teaspoons = 1 tablespoon. Hold the dog's mouth open and stick the dropper in their throat, then hold the dog's mouth shut to force them to swallow.
3. Back up and wait.
You MUST have 'fresh' hydrogen peroxide for this. To test your HP, put a little in your mouth, it should fizz immediately. If not go get a new bottle. The HP will fizz when it hits the dog's stomach, your dog may foam at the mouth for a bit and vomit a little. DO NOT bring your dog in after the first 'spit up'. Until they have really heaved a few times they are not done. It can take about 15 minutes. If they have not vomited in that time, give another tablespoon of HP.
Don't let the dog eat or drink for a few hours or they may vomit it up again. I let Ruby drink and vomit a few times to clear the bad taste out, so we just stayed in the yard for an hour or so.
Be prepared for lots of dirty looks from your dog...."
