The History of the Czechoslovakian Vlcak

Brief historical summary

In the year 1955 a biological experiment took place in the CSSR of that time, namely, the crossing of a German Shepherd Dog with a Carpathian Wolf. The experiment established that the progeny of the mating of a male dog to a female wolf as well as that of male wolf to female dog, could be reared. The overwhelming majority of the products of these mating possessed the genetic requirements for continuation of breeding. In the year 1965, after the ending of the experiment, a plan for the breeding of this new breed was worked out. This was to combine the usabelqualities of the wolf with the favourable qualities of the dog. In the year 1982, the Czechoslovakian Wolfdog, through the general committee of the breeder's associations of the CSSR of that time, was recognized as a national breed.


Where is the origin of this breed and who is the author of the idea of crossbreeding German Shepherds and wolves? It is necessary to go back as far as 1955 when ing. Karel Hartl began to work with the idea at the kennels of the Border Guard in Libejovice. The first attempts to mate the she-wolf Brita with the chosen German Shepherd were not successful. The breeding dog had to be changed. The first hybrids of the above mentioned she-wolf and the German Shepherd Cezar z Brezoveho haje were born on May 26, 1958.

Anatomical and physiological differences between the hybrids and both parental forms were examined in detailed way; their capacity for training, activity and tenacity was tested. Chosen hybrids were mated again with non-related German Shepherd Puppies from the second filial generation could be trained if they were taken out of the kennels and reared individually. Hybrids of the generations F 3 and F 4 were commonly used as service dogs in the army.

The she-wolf Brita was also mated with the German Shepherd Kurt z Vaclavky and she gave birth to the first two lines of the hybrid. A third line was also born in the Czech lands; its founder was the wolf Argo. The female German Shepherd Astra z SNB gave birth to offspring in the kennels of the Police in Bychory in 1968. The abbreviation "CV" (Czech Wolfdog) started to be used for interline hybrids.

In the 1970s most hybrids were sent to new kennels, near Malacky, which belonged to the Bratislava section of the Border Guard.

The best breeding dogs got further from the "iron curtain" And so Slovak breeders were not under such strong pressure to produce special hybrids for the army and the could work on the unifying the external traits of the new breed. The Vice-commander of the above mentioned kennels, Major Frantisek Rosik, now the honorary president of the Slovak Club of Breeders of the Czechoslovak Wolfdog in Bratislava, undoubtedly took the greatest credit for the development of the breed in Slovakia.

A third wolf - Sarik enriched the population in Malacky. He was mated with a female hybrid of the F 3 generation Xela z Pohranicni straze and with a female dog CV Urta z z Pohranicni straze in 1972. The name "Czech Wolfdog (CV)" was gradually changed to "Czechoslovakian Wolfdog (CsV)", under which the breed was later recognized. The last entry into the fond of genes of the breed was the mating of the she-wolf Lady with the German Shepherd Bojar von Schotterhof, which again took place in the Southern Bohemian town of Libejovice and the puppies were born on April 26, 1883. Kazan z Pohranicni straze (F 1), born from this mating, was used directly in breeding CsV. There has been only pure-blood breeding within the population of the new breed since. From the beginning Czechoslovak Wolfdogs got into the hands of civilian breeders. However, kennel organizations in the Czechoslovakia refused all attempts of ing. Karel Hartl to gain recognition for the Club of Breeders of this breed and at recording breedings into the pedigree register. A meeting of the Club was not held until March 20, 1982, in Brno and in the same year, the first 43 puppies were entered in The Main Pedigree Register in Prague. In ten years (1982 - 1991), 1552 puppies were recorded.
