Mine runs out ahead. I keep her under control though. I also walk my Shih Tzu at the same time and she's more of a slow pace, so I find Abbie (my Yorkiechon) looking back alot like "Come on!!!". I don't mind. Once in a while I try the "walk by my side" thing, And they'll do it if under strict control. But I truly don't care....I'm out to walk for their pleasure as well as mine, so as long as we're safe "do your own thing" is my motto. Oops uh oh,....Cesar Milan is ringing my doorbell right now to tell me off, excuse me... lol!!!
I tell you what though, if I want a nice fast paced walk for exercise, Abbie my Yorkiechon is the one to take. My Shih Tzu Jade is more built for comfort, not speed. But it's so sad if I take one and not the other.... so both go at once.
