We bought this sling 4 years ago and hoped to never have to use it again but 4 miles in to the backcountry our guy got really sick (he ate human poop with THC unknown to us..story for another time) but a 60lb unconscious dog + backpacking pack was nearly impossible. We ditched the pack and hiked him out. My partner said it would have been near impossible to carry him unconscious for 4 miles if not for the sling. Always have a save plan for your best friend!

Longest stretch 16.5m. Only issue - ticks. They say you have to hike the dogs hike - he hiked mine for sure.
