Oddly enough the easy walk is the only harness Tucker doesn't seem uncomfortable in which is strange because it looks like it'd be super uncomfortable. I would never suggest someone use it for long hikes, jogging, or for running around the park or anything very long or active like that but for walks around the neighborhood I LOVE it, yay lunge control (which you can only get from a front clip, not a back clip, harness). If we go to the park or for a hike in the woods he wears a regular harness.
I mean I wonder how long a dog has to wear it for it to cause issues. Walking funny for 20-30 minutes while on a leisurely stroll is different from walking funny for a few hours or while trying to run, climb, jump, etc.
