Frisk... a little behind me. Beside me every now and then, but tends to slow down... likes to stay a bit behind so that he can sniff and "mark his territory".
Ethan... Pulls just a little at the beginning, then calms down when I tell him to. Then he stays ahead, but doesn't pull.
Skylar... He is very much of a puller. He just gets so excited during walks. We've even tried walking him four times a day one time, but he still got equally excited when on the walk.... so he's got a bit of learning to do.
