My dog Sonny and I are so happy with the slip lead with head harness. My 17 month old Chocolate Lab/ Swiss Mountain dog was a really big puller. He would get distracted by a paper bag blowing in the wind. The head harness keeps him focused on the walk and not everything else around him. I have been struggling for months to get him to walk properly with no success, but this purchase saved me from being pulled down the street. I am so very thankful for the how- to training videos and advice. Thank you!
