Look at that, you learn something new everyday. I knew they did tests, but I guess I didn't realize how detailed they would be. But when I think about it...it only makes sense. You want the hardest working one for their specialty and just like us, not every dog will have the same specialty or desire.
Thanks for the info Michelle. it's really cool to learn stuff like that.
And yes, part of me would have loved to have seen you on your roof!
