The Československý Vlčiak, Czechoslovakian Wolfdog, is a relatively new breed of dog that traces its original lineage to an experiment conducted in 1955 in Czechoslovakia. After initially breeding 48 working line German Shepherd Dogs with four Carpathian wolves, a plan was worked out to create a breed that would have the temperament, pack mentality, and trainability of the German Shepherd Dog and the strength, physical build, and stamina of the Carpathian wolf. The breed was engineered as attack dogs for use in military Special Operations done by the Czechoslovak Special Forces commandos but were later also used in search and rescue, schutzhund, tracking, herding, agility, obedience, hunting, and drafting. It was officially recognized as a national breed in Czechoslovakia in 1982; in 1989 it became FCI standard no. 332, group 1, section 1. Nowadays, the Československý vlčiak is a national breed of Slovakia.
