I usually walk our Boston, Lexi, around late evening (7 pm) and we sometimes run but always in short sprints then walk for a bit then run some more so she won't pass out on me lol. We have taken her to the beach alot too which she is loving now that she is used to running through the water. Running with your dog would be fine just keep an eye on her so she doesn't overheat which these dogs are prone to do.
