What a puurdy face! Border Collies are so much fun(and energy). I take care of one named Buzzy and he is the greatest dog(besides my own**wink wink**). He's trained to lie down when a car passes so he doesn't have the urge to herd them, it's amazing really, he'll hear cars and lie down before I ever see them.
Good luck with the new pup. I hope you've been saving up your energy.
