I own two huskies, who walk fairly well on a leash. I thought this item would make it alot easier for me to walk the two together, but I was wrong. The clip that does the adjustment of the lenght isn't strong enough. It was constantly allowing slippage and the lenght that I had set between the two dogs was becoming larger. I would not recommend this item for dogs over 50 pounds that like to have a tight lead. My dogs don't drag me down the street, but they aren't the greatest walkers either, and this just plain didn't work for them.
