Dodi, Sabrina, Lila, Stella and Lilly may seem like strange names for wildlife
rangers. And indeed, unusual rangers they are, for it’s not their sharp eyesight
or keen hearing that qualify them for the task, but their outstanding ability to
sniff out a trail. Dodi and her pals are bloodhounds that were imported as pups
in 2011 to perform a unique function in Virunga National Park in the Democratic
Republic of Congo. Sara Evans follows their progress.
