Yeah with the first prong I had trouble with the link - was too hard to re-latch so I got the Sprenger quick release. That was hard to do at first cuz it fit snug but I am getting used to it. I also got another dog leash with the extra grab handle by the collar so I don't have to wrap it around my hand which hurts. This worked well tonight. I did try the Sporn with it and switched back to the prong - prong works better with this leash - he walked well tonight. Just gotta keep up the same routine - it's work but hopefully will pay off - I see improvement already!
