WATCH: The World’s Most Adventurous Dog Base Jumps Strapped to Owner’s Back

Base jumping is crazy enough on its own, but when you’ve got a dog attached to your back, it’s a whole new level of insanity; in a good way, of course.

Dean Potter, an adrenaline junkie and well known adventurer, owns a tiny little cattle dog named Whisper with a huge appetite for fun.

Potter told the National Adventure’s blog “All Whisper wants is to be with her pack-family. When we go on adventures, she goes on adventures. She’s just a loyal pup with a very adventuresome Papa.”

That shared love for adventure is exactly what led to the duo’s recent base-jumping stunt, with Whisper and all of her 22 pounds tucked away and strapped on Potter’s back. The newsclip above shows a snippet of the 22-minute long film, When Dogs Fly, which premiered last weekend at Mountainfilm Festival and Tour and showcases more of the twosome’s fun escapades.

Although the two push the limits, Potter assures he only brings Whisper along on the “safest cliffs in the world with the longest and cleanest rock drops.” And based on the way “she runs around and shows off and celebrates and barks and yips with joy” after a landing, Potter believes she enjoys the jumps.

Aside from the 12 times she’s jumped with him, the lively pup also accompanies Potter and his family on their swimming, surfing, paragliding, rock climbing and mountain biking trips.

And in case you’re worried for her safety, not only does Potter guarantee that he takes extreme care with her accommodations, but he’s also very tuned to her needs.

“She sends very clear signals that she doesn’t want to associate with [certain things and activities] by trembling and running away. We respect Whisper’s wishes. If she says she doesn’t want to do something, we sure don’t force her.”
