Clapham Common for dogs?

Any Clapham Common regulars here? Our little girl needs active play time and being that we're probably going to be close to Clapham Common we'd like her to have a regular crew of friends there. Walking through I saw little klatches of dogs playing but I couldn't tell if they were regular groups or random events. I supposed once we're on the ground there we'll figure it out, but just curious if anyone here is part of that scene. Thanks
