This is when the ddr breed books come in handy. It would tell you what year and age the Kor: or ZPT was tested on that dog. If the Kor or Zpt was taken at a young age lets say 2 yrs old these numbers can and were increased at a later age. Why because as the ddr matured and the hardness kicked in and in many line 3yrs and older.
The 4th number could be different at a mature age and then what kind or type of dogs do you wish to own/breed. The Gsd has been changed over the past 20 something years to tone down or remove this aggression/ sharpness to avoid liability. Today most people do not want the very hard dogs they want extreme ball and prey drive.
Aici vedem cat sunt de folos registrele canine DDR'iste. Ele iti spun in ce an si respectiv la ce vasta a fost evaluat cainele prin ZPT. daca evaluarea a fost facuta la o varsta tanara, sa spunem 2 ani, numerele ZPT pot creste / si au crescut corespunzator cu varsta. de ce, pt ca pe masura ce cainele s-a maturizat si durtatea si-a facut teptat aparenta, in multe linii, la varsta de 3 ani sau mai mult.
Al 4lea numar se poate schimba o data cu inaintarea in varsta si atunci poti cunoaste ce fel sau ce tip de caine ai vrea sa deti / cresti. CG'ul a tot fost schimbat de-alungul ultimilor aprox 20 de ani pt a inmuia sau reduce aceasta agresivitate / ageritate, pt a se evita raspundere legala. In zilele noastre oamenii nu mai vor cainii duri, vor cainii cu super drive si super-aportori.
