Recently, we've been on a few hikes that turned into bigger rock scrambles. My pup was struggling to get traction to get over them and just had a few bobbles that made me wish I could assist. We usually turn around at this point because I never want to put him in harms way. This new harness is the answer! Now, I can help him up AND down things that he's unsure of and get him safely through these sections. I've been a long-time fan of all of the Ruffwear harnesses but this one is just so functional and light. It doesn't seem to bother him, even on the hottest of days. I highly recommend this harness if you want good stability and the option of lift-assist for your pups.
