My new BT, Cosmo, is like this. I love it, as we've had many high energy dogs - boxers, springers, a Sheltie, and this BT is just what I like. My only regret is that he doesn't play with our 3 yr old Sheltie, Maisy, at all. She whimpers at him, and he sniffs her, and then takes a nap. He will get up when I do and, with Maisy, follow me around, curious, but after a minute or so, he's curled up somewhere in a ball.
