"The MDT hands-free leash" is an 8ft long slip/clip combo that can be used as a slip leash or clipped to a prong/collar.  There's a clip in the handle that can be attached to the floating ring with 2 additionals stoppers for a custom fit and many different uses!
 
Here's what Brittanie McGee from McGee Dog Training in Frisco, Tx has to say about her custom leash:
You can put it over the shoulder or around the waist for a hands free walk.  You can clip it around a couch leg to tether your dog while teaching place/setting.  You can use the 8' length to practice recall or for a sniffy walk...the options are endless!
 
Brittanie offers virtual lessons, but if you are in the  Allen, Texas area reach out to her for private lessons and/or board and trains.  You can find out more about her and her training packages here.
