MEMBER SPOTLIGHT REBECCA TROTH and her dog Teagan For the last six years, walking Teagan 30 to 45 minutes a day has been my main form of exercise. Although Teagan is blind, he is always willing to trot along, confident that I wouldn't let him walk into cars and mailboxes, and for the most part, I didn't! Troth is executive director of the D.C. Bar Pro Bono Center.
