Hello, Myra!

I am sorry you didn't get the attention you deserved at the PetsMart class.

The Monks of New Skete are now considered "old school", he hee. So please be cautious as to what you take from their book.

On to the lunging. Just what Karen said!

This is what was trained in the classes I took:

You want to teach "Watch Me" where the dog focuses on you. While feeding the treats as in the yahoo link, the dog should be sitting, facing you. The dog should have it's back to the passer by, and a good clearance distance. You may have to mvoe off a path or sidewalk onto grass to give the other dog walker room to pass your dog without being too close.

It will take time, persistence, consistency (all as Karen said!)

You may want to consider an Easy Walk harness. The leash attaches at the chest area. So the dog pulls and this spins the dog around to facing you. I have heard good things about it, but never used one. In classes, twice the instructor suggested it, the people bought one and next class they were pleased with the progress they were making. Here is a link to show you what it is:
