I'd also like to understand the reasoning behind this thinking here. I don't know anyone whose dog knowledge I respect who keeps "conformation only" dogs (in the sense that the dogs are not also house pets and/or working dogs), and I know LOTS of people who have titled many dogs front and back whose dogs are well-loved house pets who also compete successfully at agility, herding and obedience and some who are not only conformation and performance titled indoor house pets but who are ALSO working farm dogs (Rakki's breeder's dogs are ALL indoor pets, ALL her breeding stock are at least conformation titled, and most are also performance titled, and most of them are also working farm dogs who herd sheep, since she owns a farm). Sounds like a load of hooey to me, not least since I've seen far too many cases of extremely successful (in competition) dogs who were raised exactly the opposite way that this individual suggests (not to put TOO fine a point on it!).
