Remember top trainer doesnt = top competitor. Many top competitors only own and train a certain type of dog. They buy the dogs green and even then go through a bunch of them to find that perfect dog.
We had a WUSV competitor at the club a couple weeks ago. He only keeps and competes with dogs he can bring out in defence. He tried to do that with a couple of club dogs..and didnt work out so good. He is a world class trainer/handler but only with a certain type of dog.. If the dog doesnt work the way he likes its on to the next one.
Such shy animals are in all circumstances an encumbrance to their owner, who must be ashamed of such a dog, and a disgrace to their race. Under no circumstances whatever must they be used for breeding, however noble and striking they may appear.
