Architect Christine MacNeill started the Doberman Gang of NYC in 2013 in part to find playmates for her high-enegy puppy, Lucy, and to find like-minded people who love the breed. Today, the group, which has 60 members on its Meetup page and has all kinds of dogs, from show dogs to shelter rescues, gathers regularly to burn off the abundant energy--both physical and mental--for which the Doberman Pinscher is famous.
