Yep, but they are considered 'ultra high energy' for a reason. When our BC mix was a pup, we would go on two to three walks a day at 1-2 miles each walk. Just so she'd calm down at night. She'd want to be good, but just have soo much energy...
I know the OP said no mutts, but i think that is too bad. I know you can't 'verify' what breed the dog will be, but mutts are usually healthier than pure and often the 'quarks' of a breed will be lessened by the mixing.
Our BC mix got the energy and intelligence of the BC, but none of the herding instincts, which is nice around kids. I bet if you looked around, you'd be able to find some mutt puppies from two pure bred dogs pretty easily.
As others have hinted at, just because it's a pure bred dog, doesn't mean it will get all the traits of the breed. Both in good ways and bad.
These are no longer called mutts, these are now "designer dogs" and can be quite expensive.
