In the year 1955 a biological experiment took place in the CSSR of that time, namely, the crossing of a German Shepherd Dog with a Carpathian wolf. The experiment established that the progeny of the mating of male dog to female wolf as well as that of male wolf to female dog, could be reared. The overwhelming majority of the products of these matings possessed the genetic requirements for continuation of breeding. In the year 1965, after the ending of the experiment, a plan for the breeding of this new breed was worked out.
