We used a Halti on our old cocker when she was young as she used to pull so much I worried about the damage to her little neck, we did use it for several years, stopped at about five I think, they are fab and seem much kinder than a collar, our Lab puppy went through about six, he worked out how to pull it off with his front paws and chew it if we wern't quick enough putting it back on lol. hope you have continued success with it. xx
