Spring is upon us, and with it comes fresh ideas and new beginnings. What better way to greet the new season than to meet our new friends—Bark’s Fab Four cover pups will win your heart. The theme of “natural” dog is woven through this issue—the ways that dogs bring us back into nature, helping us discover or reconnect more fully with our environment and realize the importance of protecting it. We talk with Karsten Heuer about his family’s mind-boggling adventure to “find” Farley Mowat, which involved a canoe trip across Canada with their Border Collie, Willow, and two-year-old son, Zev. We also talk with a true hero of the green movement and a MacArthur “genius” award winner, Majora Carter, whose dog, Xena, led her into an area of her South Bronx neighborhood that awakened her resolve to reclaim it for her community.
