Be sure and tell the dog that he/she is a "good dog" after she corrects him/herself.

I went to obedience school with two dogs - at the end, could do figure 8 walks and the dog knew when to slow down, and when to speed up, depending on wether she was on the inside or outside of the turn.

Yank, then say Heel - then say good dog (when appropriate). "No's" should be firm - not wishy washy No's - say it like you mean it. Sometimes a doggie treat can help with encouragement.

Good Luck!
