Just received the leash coupler and I love it! I previously had the Susan Lanci zebra collar and leash for my two yorkies, Coco and Lollia, and they are wonderful. The coupler matches perfectly and will be great when I need to put them in a space that only allows for one harness to be secured. Now I do not have to worry about safety and can keep them close to each other as well. We are looking forward to using the coupler. Thanks GW for catering to my little ones.
