Wow,I really opened a can of worms!!!!!!
What needs to be remembered is that no breeding program produces a 100% return of the desired traits it is trying to produce.The reason that most people fail in getting a higher percentage of desired traits is because they don't adequately test the pups at 7 weeks,which cynologists agree is the age at which a dogs personality,or the main traits are already determined in the dog.However,no matter how good the parents are,the breeder is never going to eliminate the effect genetics has on the litter,so even the most intensive testing of a pup cannot rule out the genetic and new environmental variables that are out of your control.
Take for example,breeding Guide Dogs for the Blind:Australia's breeding program is world renowned,with many dogs bred here being exported around the world,however,the breeding master has stated that only 30% of the pups born will be successful in graduating to become a working dog,and Australian Police,who also have a breeding program for GSD and Rottweilers have found similar results.
What does happen is, that as a dog breeds function becomes less necessary or desirable,and it is bred solely for looks or companionship,it's working desire and ability either decrease and become non-existent,or it becomes a liability eg the Pit Bull Terrier.
My answer to the lack of CSW's & other working dog breeds gaining,and maintaining their working status is to encourage people to join dogsport clubs and have professional experienced trainers guide you thru the training regime,working out the best method of training for the dog,and as harsh as it is,if your dog is unable to attain a sufficient level of proficiency,don't breed it just enjoy having a beautiful loving companion guardian in your life.Of course,for those countries that don't have a large population available to do this,don't breed the shit out of them,just be careful how you breed!!!!
