I was looking through these and was wondering if there is some way of grading each individual activity, instead of the overall category. For example: herding. I've tried Pixie on sheep, and she shows no instinct for it, but was perfectly happy to chase them around. Treibball, on the other hand, she loves. So I don't know whether I should say that the herding category in general is a good match for dogs like her, or not. It gets even more complicated when there are 6 or more sports lumped together.
