The Czechoslovakian Wolfdog (Czech: Československý vlčák, Slovak: Československý vlčiak, German: Tschechoslowakischer Wolfhund) is a relatively new dog breed of wolfdog that traces its original lineage to an experiment conducted in 1955 in Czechoslovakia. 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-sport, tracking, herding, agility, obedience, hunting and drafting in Europe and the United States. It was officially recognized as a national breed in Czechoslovakia in 1982, and was officially recognised as a breed by Fédération Cynologique Internationale (FCI) in 1989.
