I actually prefer the Easy Walk over the Halti The clip that attaches to the leash is on their chest. When they start to pull, a gentle tug instantly pulls them sideways and back into position. It's pure physics. Once the pup is back at your side, treat and reward and move on.
Of all the harnesses that we sell, this is probably the top seller. I rarely have one returned.
I do hate seeing dogs in harnesses 24 x 7. My groomer and I both cringe because of the matting. Believe it or not some people leave the harnesses on 24 x 7. I've heard my groomer trying to gently tell them no to that.
