I am looking at a nest that has to be born with the father having a ZTP 1B U and the mother ZTP 1A SG. Am i correct in amusing that the U (excellant) and SG (very good) is on the confirmation of the dog itself and the ZTP 1 A/B on their working abilities? Both parents have VPG 3, im amusing this is the german IPO? Does ZTP 2 exist? or its just A or B or fail? been searching the net but couldnt find anything concreet on the matter.
