Running Away

So yesterday it was nice and hot out, so I took Monty for a nice long walk. We came home, and my neightbor was playing fetch outside with her chocolate lab, so we decided to play for awhile with them. I took Monty of his leash so he could run around with the lab, and that little bugger took off down the block! He would run a bit, stop and wait to make sure i was coming, then run a bit more, wait for me to almost catch him etc etc. My neighbor said her dog would NEVER do that, that she knows better. How come Monty doesn't?! I know he's just playing, but after 10 minutes I was DONE playing, and he wouldn't listen to me /forums/images/%%GRAEMLIN_URL%%/frown.gif

Justin says that Monty doesn't see me as a leader, because I'm always the one playing, and not disiplining him. How do I make Monty respect me without hating me?!
