I do not know your breeding regulations in Italy. The best thing to do is to contact the studbook office of the SV or the WUSV directly.
From Germany, I understand the blood sampling is done to all the puppies at the time the microchips are inserted, consequently, if the parents do not have the biological sample deposit, the born puppies cannot be registered in the herd book SV, and cant have the "pedigree" right?
That is correct.
