Fortunately, no one told me before I fell in love with them that German Shepherds shed, a lot, all the time. Hard surfaces they just come right off of.
Textured fabrics get a little more interesting.
And furniture has to be substantial. Delicate just doesn't stand up to kids or dogs. Oh, one more thing. Pick a vacuum cleaner you don't mind looking at - it'll probably be left out more than it's packed away. We use the blue bags in capsules when we are out in public for their convenience and aesthetics.
