Leash training

So I'm working on Coda staying close to me when we are walking, using a flexible leash... Currently, when he gets to the end of the leash I make him come back to me and treat him when he is in heel position on my left side. Tonight there were a few times when he deliberately stayed close after I had given him a treat. I also spent some time in the top parking lot of Union Mill repeatedly doing turns and treating for times when he was close...

Also, new triumph... Am back walking 1 mile :)
