That all depends on what kind of space I got atm. But I will wait until they are 3yo. I don't necessarily keep the dog here at all times. If not started up by that age I usually sell them as pets or give them away to friends. I don't see any dogs as waste of time or money. I can put every dog to a different use, even if I have no use for it. A cold dog could work perfect using as a "playmate" when conditioning other dogs. He could be a perfect pet for a friend of mine or a family member. Might do well as a guard dog or a weight pulling dog. The only dog that I put down are a dog that either bites or quits. Otherwise I find a use for every dog.
