Czechoslovakian vlcak (CSV)

The Czechoslovakian vlcak (click to hear it pronounced) is a breed

developed in what is now the Czech Republic and modern Sovakia.

The breed began as an experiment in 1955 by the military of the CSSR. 


The military admired the German Shepherd dog for its athleticism,

trainability, and use as a working dog. They wondered if it would be

possible to improve upon the German Shepherd and create a uniquely

Czechoslovakian breed. They believed it might be possible to do so by

breeding select German Shepherd dogs with the Carpathian wolf, which

is native to Eastern Europe and possesses robust health and endurance.


The first male German Shepherd dog to successfully breed with a female

wolf was Cezar z Brezoveho haje. A second line was developed via the

male German Shepherd dog, Kurt z Vaclavky. Their offspring were used

by the police and military of the then-CSSR.

Modern CSV are not "wolf hybrids." They are acknowledged as a dog breed by the American Kennel Club, which does not allow wolfdogs in their registry. As new wolf content has not been added in decades, the temperaments and physical appearance of CSV have been standardized and lack the unpredictability of recent wolf/dog pairings.


Dog experts and trainers have noted that the Czechoslovakian vlcak has a superior sense of smell, intelligence, overall health, and much greater endurance than the German Shepherd dog. They excel at tracking and at endurance trials which require them to run up to 100 km (63 miles) without flagging. 


Czechoslovakian vlcak are currently used across Europe as bomb-sniffing dogs and for search and rescue. They are also shown in FCI dog shows in Europe and Asia, and are qualified to register with both AKC and UKC.


For training, Czechoslovakian vlcak require consistent and calm leadership. For this reason, they are not recommended for first-time dog owners.
