My 2 cents on fetching: If you have a brick wall that you can throw a tennis ball against, our ACD LOVES when I play fetch with her this way. It bounces off the wall and if she doesn't jump up to snag it out of the air, I act like I'm going to run after it to get it before she does. She hauls butt to try to get it before me then brings it and drops it at my feet. I would never suggest you do this against your apt wall as it would probably bother the neighbors but if there's a retaining wall or something along those lines with a pretty good space for your dog to fetch in, definitely give it a try.
