My dog and I are avid hikers and enjoy regular hikes ranging from 3 miles to 15 miles. The pack is sturdy and I like the handle on the back as we have A LOT of wildlife here. I wish that there were 2 buckles on the front so that the pack could go on just over the head, not over the head and then thread one front leg through. Adjusting the straps for proper fit is easy and the straps are thoughtfully located.
