Unless she starts having a seizure or vomits blood, don't worry.

If the dog needed a walk it'd be more hyper.
Due to the ridiculously high amount of assumptions we can make by your description, I'd suggest taking him to your local veterinarian, as opposed to getting advice from people on a forum about building blocks.
