Sorry bryt, as I said, most are just naturally reasonable dogs, and adjusted to do only what they need in the ring.
Many "obedience" dogs are also adjusted only to the ring, and outside it - it's a different story. Much moreso with conformation dogs.
My experience is they are not trained. Period. No more than any of the other pets in the regular world, who similarly believe it's "cruel" to make a dog contain himself with self-discipline never mind commands. And it was indeed a mantra that truly training them would ruin their attitude (horse-hockey as my Shana would tell you; even my less-controllable schizo Tara would tell you that).
It's merely a matter of being lucky they are amicable and not hyper and schizo.
Yes, I've heard that old saw, train them and ruin them for show. My first show girl did obedience, hunt tests and conformation, often conformation and obedience on the same day (I wont do that again, it's too hard on ME).
I have to admit to more laziness now in my old age, but all of my dogs are better trained than most house dogs because of I am intolerant of idiot dogs running around annoying everyone! ;)
