I am so glad to hear that she probably is totally okay, just getting used to the summer.
On the parvo note though. If they are vaccinated, they can still get it. Not very bad, and totally unlikely to the point where they get severly sick. But a dog who is vaccinated and exposed to it, can show signs like a slight elevated temp. tired and just feeling off. in some cases they dont even had the runs or vomit. A lot of dogs actually have it without the owners even realizing it, well that is for the ones who are vaccinated, if not you cant really miss it.
I hope she is feeling all back to her usual self next time you update us
