If you are hoping for this to correct your dogs walking then I 100% suggest it. It was like magic, my dog immediately just walked perfectly beside me without pulling. I honestly didn’t understand it. But I have a very large 130 pound dog who is much stronger than me. I was hoping that this would allow me more control when he pulls hard towards another dog but it actually seems to give him more strength. The leash is also starting to fray after just a few weeks.
