I think that there is a ton of value in teaching foundation, breaking down sequences and working all the pieces and parts of the exercise/course. I also believe that there is tremendous value in just powering through a course, not giving up, and learning to improvise with what the dog gives you. They aren't always going to do what you expect. :)
I am taking Silvia's Handling 1 class with Hoot. This morning I set up one of the courses and decided that "powering through it" was my objective. I ran the course with both Tangle and Hoot. You can see that both dogs reacted slightly different on this course and we powered through.
When I was running this course with both dogs I was being a bit conservative. I want to re-run it "balls to the wall" so da speak and see what kind of commitment and trust we have in each other.
