Vicki, not all dogs. I've owned German shepherds all my life mixed in with a few Heinz-57s. The only dogs that got clipped were the ones that had long hard to manage hair (me on a humid day).

Now a few of the other breeds with "speciality" coats do. They require a little more on the grooming side than most flat coated dogs do.

Please post a picture, I've always wanted to see what one looked like.

(ps. the thought has run across my mind to shave mine too).
