This tangle free leash is heavy duty, sixteen feet long and has a one button control. It is intended for medium to large dogs that weigh but to 110 pounds. The leash is retractable and works great for letting the dog go further but still having control over your dog. The handle fits nicely in your hands and is not too big or small. There is a break and lock device that makes this leash the best on the market. We really enjoy using it.
