seriously - get a dog along the lines of a border collie or standard poodle - the einsteins of the canine world.
you MUST walk them twice a day - such high-energy dogs require a minimum 45min walk a day PLUS they need exercise (walking is *so* not "exercise" for these breeds!) and then they need jobs - that means you need to train them.
you'll be moving and shaking in spite of yourself!
the caveat is that if you try to skive off on the walking, they'll usually demo your house and be a total pita until you get it in gear.
