What can I say... Your system has been the ONLY one out there that can handle my 2, overly excited, 120 lbs Rhodesian Ridgebacks! Wow, what a spectacular leash system. This is the only hands free system I will ever use. The design and feel of this system makes it a breeze to use. I give this product a four paw stamp of approval! Trust me this is the only system you will ever need for WALKS & RUNS! I should know, I've tried 3 other different Running-Leash types and there is no comparison.
