I still think about that class, and know that I am lucky Kipawa and I left when we did.
Kipawa has come along marvelously. I remember that trainer saying that by the end of our classes, our dogs would be walking beside us with our leashes forming a nice loose "J". I wonder what sort of method she would have used for that. A broom? Okay, that is a little catty of me, but probably something like that would not be that out of line for her training methods.
I found it quite simple to do with Kipawa, using positive reinforcement. I usually carry a few treats in my pocket, but now he thinks I always have treats in there. It works very well.
It would have been nice to know how things worked out for the couple that had Kato. Perhaps I will see them in a dog park one day. They were really nice, as was their dog. Their dog just needed to be worked with more.
