Hey Jeff. I'll have to go back and read David's blog.
I quantify enthusiasm very simple. Scale of 1 to 5. In practice, I'm finding some fuzziness. For example, sometimes she'll start at a "3" and then the last run of the night is a "5". So I've been logging it that way: "3 to 5". Other nights, it might be "5 to 3".
And that fuzziness is ok. In this very specific example, I'm just trying to get a more accurate picture of her level of enthusiasm now. Then, after implementing a training program focusing on enthusiasm, I can see if I've made progress.
I'm off to dog class, so I have to go. More later!
