For the most part, I don't even hold the leash, it's simply there to prevent him from complete escape, or finding a woodchuck burrow.

Hell one day he got really pissed at me and didn't want to come back into the house, He drew blood on me after I did actually catch up to him.

Once he decided to hit "full throttle" it was a challenge to catch up.
