I have used the Buddy System hands free leashes for some time now. I just recently switched to a different system because of one reason. I am an older person, and I don't run, I walk. When walking my two small dogs on this system, they would sometimes tangle around my legs, causing a falling hazard. Be aware of this if you are going to walk more than one dog at a time and you are older or very frail, it is a serious problem. Most of the time, my dogs walked fine with no problems and it was a HUGE help to me that they could not run away from me as they are very fast, and I'm not, but they are also pretty strong and when they wrap around you, it is a problem. Other than that, I loved the convenience of this system and even bought a second one to keep in the trunk of my car!
