We noticed a big difference in walking our dog immediately, during the very first use. In the first half of the video, the leash is attached in back, like our normal harness, and you can see how his front legs are lifted off the ground trying to run. In the second part, the leash is attached in front, for no-pull; this was only the second time we used the no-pull attachment with him, so you can see that he still tries to pull some, but the difference is dramatic! (also, my son should have been walking to the dog’s left side, where the leash was, but we were just learning, and the dog likes to switch sides while walking) I am confident that with regular use, he will become used to it and stop pulling completely. (Of course, the true test will be when a rabbit or squirrel crosses our path!)
I’m no longer skeptical and I love this harness!
