Deutscher Schäferhund
In 1955, Ing. Karel Hartl began to consider crossing a Carpathian grey wolves with a German Shepherd (, , ) as a scientific experiment at the military kennels in Czechoslovakia. A few years later, however, the idea was born to establish a new breed. The first hybrids of a female wolf named "Brita" and a male German Shepherd named "Cézar" were born on 26 May 1958 in Libějovice.
