Well our first dog, Rusty, is an Airedale Terrier. And he was bad ass when he was a puppy, and he's still a bad ass nine year's later. Tons of energy when he was a pup. Excellent temperment. Great with all walks of life, young or old. Doesn't shed. Was easy to train. And now that he's an old timer, he's very chill. Still has plenty of energy to go have fun, but loves his relaxing time.
