Millie and I have been doing agility for a couple of years. She earned her C-ATCH and has title in other venues also. She is one of the reasons I need to lose the weight. It is very hard to keep up with a Border Collie on the corse.
She is beautiful!! I'm sure she'll help get you in shape! =0)
My dog is one of my biggest motivators. He wants to exercise CONSTANTLY. And he needs it. He's husky/lab so not as hyper as yours but his endurance and energy are outrageous. Even if I don't feel like getting my butt of the couch, he does so we go go go!
I always wanted a border collie when I was a kid. Such a pretty girl she is!
