“Whisper” is the first dog in the world to ever experience base jumping in a wing-suit. According to Dean Potter, owner of the Australian Cattle Dog, Whisper was always up for an adventure. This story always prompts a lot of comments, but we’re sharing it to give props to the breed.  An addendum: On May 16, 2015, Potter died after attempting a wingsuit flight from Taft Point, a 7,500-foot promontory that overlooks Yosemite Valley and El Capitan. “Whisper” was not with him.
