The first efforts in crossing dogs and wolves were documented in the 1950s in Czekoslovakia when wolves were crossbred with Border Guard Dogs at military kennels. Four Eurasian wolves (Canis lupus lupus) were used in the experimental crossing: two males (Argo and Sarik) and two females (Brita and Lejdy) as well German Shepherd dogs. Breeding wolf-dog hybrids was a very difficult task. Some dogs became very aggressive. One of the dogs attacked the handler and had to be destroyed. In late 1950s the breeding program at the Border Guard Dogs kennels was discontinued.
In 1983, Stanislav Marsalek bred his she-wolf to a German Shepherd Dog Bojar von Schotterhof. Bojar von Schotterhof was an all-purpose working dog which was used as a guide dog. The she-wolf, Lejdy, was placid and tame. One of the puppies, Kazan z Pohranicni straze, was a huge dark crossbreed, similar to German Shepherd Dogs. He was trained as a tracking and guard dog and successfully passed a few tough obedience tests. Later, Kazan's offspring were used in a breeding program to develop the Ceskoslovensky Vlciak (Czeslovakian Wolfdog), which later was recognized as a national breed.
The Czeslovakian Wolfdog is a magnificent animal of striking beauty. His shoulders and chest are massive and deep. The darker markings on his face set off a pair of beautifully expressive eyes. In winter, a dense undercoat is formed, and, together with the topcoat, forms a thick coat all over the body. The hair covers the belly, the inside of the upper thigh, the scrotum, the inner part of the ear and the area between the toes. The color is yellowish-gray to silver-gray with a charateristic light mask. The hair on the underside of the neck and the forechest is of a lighter color.
The Czeslovakian Wolfdog is a fearless, courageous, and tremendously loyal dog. Naturally suspicious of strangers, he makes an outstanding guard dog. He bonds with all members of the family and quite tolerant of children's rough play. The puppies need to be socialized with people and other pets and animals at a very early age.Czeslovakian Wolfdogs need a lot of space, exercise, and a companion to thrive.
