This harness has been a game changer for my girl, she hates a harness continously rolls on the ground, she is a very anxious girl on walks, she pulls terribly, I decided to give this one a try as my last resort she has had so many different harnesses, but this one is amazing she does zero pulling, she seems calmer, no rolling around on the ground, it's just made her life alot easier on her walks. Thank you
