Short and Sweet?

It was cold today but we worked dogs.  I just did one turn with Rave.  I have cones set in a line, like agility weave poles, and we attempted to drive-weave through them.  A good test of my fine control and 'aim' but not sure it was good for Rave.  She couldn't figure out why I was flanking her back and forth so quickly.  I think she thought she was doing something wrong.  Its a good exercise but not sure if it is accomplishing what I wanted.  I think perhaps it is a better fetching with no commands exercise.  Making sure that she squares at each change of direction.
