This works so much better than the rope and carabiner I rigged up on my own. The design allows for easy tensioning (vs me having to figure out knots and adjust as the rope stretches). I also love the carabiner with a ring, which slides along the rope much more smoothly than a straight carabiner and also feels more secure. My dog has lunged and pulled on this pretty hard with no issues at all. It's the perfect way to have her out with me at camp without being off-leash or getting wrapped up in a tether. I do supervise her 100% while she is on this, but it makes camping much more fun for both of us.
