Originally bred for laboratory purposes by František Horák in Prague in the 1950s, the breed is now primarily a companion dog.

[1] Czech cynologist František Horák wanted to create an ideal dog for laboratory work.

He described the desired characteristics in 1954: suitable size, smooth coat, high fertility, good nature and low food consumption.

There are some speculations about successful transplantation of kidney because František Horák wrote a short note about it.

The existence of the breed remained a secret for the public until they were presented on a dog show in 1961.

Despite the promising start, the breed wasn't accepted as well as expected and the dogs were on the edge of extinction.

The structure of the body is harmonious and not too heavy, with a slightly rectangular frame with folded ears.
