Apart from their incredible tracking abilities, dogs are wonderful to work with because they don't have any political agenda—they can't be compromised," said Damien Bell, director of Big Life Tanzania, the conservation organization that manages the Big Life Tracker Dog Unit.
"Our dogs have tracked elephant poachers for up to eight hours at a time or more, through extreme conditions—heat, rain, wetlands, mountains—and still turned up results," he said. "They love their handlers, and they do a job until the job is done."
