Just received this a couple days ago and already love it. Now I can run, skate or ride my bike and keep my dogs right next to me. One warning, though. Instructions indicate you can leave the collar clip attached to the dog's collar. I don't recommend that as it can hang down just enough for your dog to get it in her mouth and chew the clip. The company was nice enough to replace the clip when I called them so kudos to them for doing that. I've added the Add-A-Buddy, Extend-A-Buddy, and Lunge Buster accessories so I can walk my entire pack at once. I have a Husky, an Australian Shepherd/Border Collie mix, a Pug/Chihuahua mix, and two Chihuahuas. The Buddy System has small dog and regular dog extensions so walking all five dogs at once is easy. It's quite a sight to see me walking down the street with five dogs attached and my hands are still free to offer treats, give hand signals, or carry a couple toys. I'll have to make a video review at some point soon and post it here. In the meantime, if you want to walk or exercise with your dog and keep your hands free this is the system to use.
