This is Whisper, 22-pound Australian Cattledog.
The dog’s owner, Dean Potter, is a ‘rock climber, walker and human-body-flyer’ by his own description. Potter brings Whisper when he BASE jumps from mountains.
This video is a jump from the 13,000-foot Eiger in Switzerland.
Potter wrote a blog post, saying the dog secured by a harness that’s as strong as those designed for humans.
