King is Aussie wolf mix is half high energy and half low, when you take him for a walk you have to watch it or he will power walk himself into exhaustion. But if he is not on a walk he is pretty low energy. I agree with Jazz, smartest dog I have ever owned. I spent 6 weeks trying to get him to roll a ball back to me with his nose, every time I did it he just looked at me funny. One day John tossed it to him and he hit it back in the air with his nose. He liked real ball not baby roll ball.
