The Czechoslovakian Wolfdog (Czech: československý vlčák, Slovak: československý vlčiak, German: Tschechoslowakischer Wolfhund) is a breed of wolfdog that began as an experiment conducted in Czechoslovakia in 1955 by colonel Karel Hartl together with cynologist Heiri Machat. The breed was known as Czech Wolfdog (Czech: český vlčák, Slovak: český vlčiak) until 1982.

It was officially recognized as a national breed in Czechoslovakia in 1982, and was definitively accepted by the Fédération Cynologique Internationale in 1999.

History

History: In 1955, Karel Hartl began to consider crossing a Carpathian grey wolf with a German Shepherd as a scientific experiment in the military kennels in Czechoslovakia. The first hybrids of a female wolf named Brita and a male sable German Shepherd named Cézar z Březového háje were born on 26 May 1958 in Libějovice, Czechoslovakia (modern-day Czech Republic).

The Ceskoslovenský Vlciak was definitely accepted by the Fédération Cynologique Internationale in 1999, listed in its Sheepdogs and Cattledogs group of breeds.

In 2012, the breed numbered 168 bitches and 170 dogs officially registered in the Czech Republic.
