A crossbreed between a German Shepherd and a Carpathian wolf, known for its wolf-like appearance, intelligence, endurance, and strong pack instincts. It thrives in active environments due to its high energy levels and is known for its loyalty and trainability. The breed plays a vital role in search and rescue operations.

The Czechoslovakian Wolfdog, also known as the Czechoslovakian Vlcak, originates from the region that was formerly Czechoslovakia, which is now the Czech Republic and Slovakia in Central Europe.

The Czechoslovakian Wolfdog is suited to temperate forest environments, characteristic of Central Europe. These regions typically experience a temperate climate with distinct seasonal temperature variations, including cold winters and warm summers. The areas are often forested, with a mix of deciduous and coniferous trees, providing a natural setting similar to the wolf's habitat.

Originally bred as a working dog for military purposes, the Czechoslovakian Wolfdog exhibits high endurance and adaptability to various terrains, ranging from forests to mountainous areas. Their ecological niche involves roles that require agility, stamina, and the ability to work independently, reflecting their wolf ancestry. As a hybrid of the Carpathian wolf and German Shepherd, they have inherited traits allowing them to thrive in environments where they can utilize their keen senses and high energy levels.
