That is an issue more with owners who don't know better or are just lazy and poor at training rather than the dogs themselves. All dogs do better with activity, but even Border collies, (Long ago and far away I owned, trained and worked a pair), don't work all day long every day. Most days they might do 30 minutes of actual work. The rest of their time is spent lounging in the sun or shade. So it's less about energy and more about training. The one thing a working breed from a proper bloodline has over a lot of rescues is tractability. No matter how "high powered" they might be, if they are not willing to easily do your bidding, even at a long distances, they are worthless. Tractability means as much or more than drive.

Again, don't get me wrong. Rescues deserve and need a loving home as much as you or me. I have a rescue dog myself. His only requirement is to do tippytaps for his kibble, soak up butt rubs, (because who among us does not love a good butt rub), and keep my feet warm over the winter. But he came from a harsh place and was a very stubborn and willful dog to work with. It took me nearly 2 years of training effort to get to the lovable house pet he has become. And I'm a very highly and experienced trainer - more so than the vast majority.

Your dog is a reflection of its owner/handler/trainer.
