Good lines produce good dogs. Maybe not every dog, but on the whole, good dogs. But great dogs, they are rare and a lot of people feel they should be bred. They will probably produce good dogs, but they might produce a great dog. I can understand how someone who is following a dog because they like that dog, or who is very familiar with whatever dog-sport might be totally disappointed when they hear that a dog has been altered.
I think from a breeding perspective, we want to produce great dogs and it doesn't really matter what lines we are talking about. We are matching up the best of the best to the best dog for her in hopes of creating some very exceptional pups. When your think is going to take 1-2 years to determine whether this dog is everything you hope for, there is just no way you can keep every hopeful. So you place them in homes that you feel confident will do everything to give that pup its best shot at reaching its potential.
I really don't think that continuing to trial after a dog is altered proves the lines. It does, but since littermates are not identical, breeding a littermate of a truly awesome dog doesn't give you the same chances of reproducing the animal that was altered. In fact it can't, and neither can breeding the truly awesome dog, but that is the dog that we would want to breed.
I am guessing that people will sometimes sell these dogs with a pick of litter if ever the dog is bred clause built in.
