I purchased this along with the separate dual carabiner for my two pups (100lb lab and 55lb pit mix) after happening upon a large loose dog one night while walking my two pups. At that time, I realized that my hands were full with leashes, flashlight and doggie bags and I felt defenseless. We’ve used it several times already and I LOVE it! It comes with an attachment for holding doggie bags (new and used). It has so many different accessory options, and I’m looking forward to adding a few in the future.
