Hello Massimo, here in czech republic exist "working blood line" of course. In this bloodline are some wolfdogs, who has not exams. But you can see, they have working possibility. They love training, aport, barking...... The breeders of wolfdogs in czech republic know, what dogs are very good for training and what puppies from some parents can be good for it. Quantity of exams of parents is not important. Important is working preconditions. I know more wolfdogs with this characters. And not all have some exams.
