dog range qustion

I don't know why, possibly just bad luck or poor dogs but I have honestly never hunted with a dog that would "cast" (without being on a trail or running) that would make 3 mile circles. Once on a track I would not expect any of my dogs back until I catch them but just looking is another thing all together. How do you guys trash break these dogs that go that deep. Seems like as youngsters they would commonly be on off game while on these wide hunting missions. The main reason I keep my dogs close is so as young mischevious pups I can tell when they are goofing off. A dog I could 100% trust that would cover that much country would difinately be an asset but I just can't see how correction at an early age would be possible.
