I'm one of those people who has a fabulous dog, his potential far outweighs my handling skills or so I've been told but I have lofty goals for myself so we'll see..haha. He was purchased as an IPO dog and that's exactly what I've been doing with him, club training once a week but we do a little bit of training on a daily basis.
Even if something happened and he became a straight pet (he's still a pretty big pet) I don't think he'd ever be a couch potato as he's way too much dog to be content just laying around.
So assume, for arguments sake, that something awful happened and you were unable to continue to compete. What would be the plan then? Could he handle being a pet or would your goals just change?
