I think it's still new to them. Tire them out good before bringing them back inside? I had a foster that played and played. 70 lb GSD and 70 lb dobie raring thru the house. I would put them in a sit, or down, near me. They would settle eventually. 
Thanks! Every once in a while I get a glimpse of settled dogs, and then there's a sound and they're off again, but it gives me hope! It's not like I'm surprised that 11 and 18 month old, high energy, working line puppies are insanely busy! We're having a blast with him though, he is SUCH a sweetie, and actually he is the less intense of the two.Hang in there!
