that gypsy dog looks hot as eff, too bad about her being barky. border collies shouldn't bark much, but with mixes, you never know.
on border collies/exercise (my experience). they're very athletic and like doing athletic things, but they really just like doing what they like doing and the running and jumping and whatnot is incidental. so if you have one that likes balls and fetching, just tossing the ball to it in your living room while you watch tv is just about as fun for it as taking it to a park and having it run to chase down the ball.
