Prague Mouse History and Fun Facts

These dogs come from the Bohemian area, in what is now the Czech Republic. There are documents that trace their origin back to the Middle Ages, a time when they were considered highborn dogs and were among the preferred varieties of local aristocrats.

Over the years they became popular with city dwellers, who used them to get rid of rats. They were especially valued during the era of the black plague, as they were specialists in hunting these rodents, the main transmitters of the disease.

In the late 19th and early 20th centuries, with the arrival of larger and more versatile dogs, the breed fell into progressive decline. For decades they continued to breed on farms and in isolated rural areas of the Czech Republic.

In the last years of the 20th century, the interest in these little ones shot up again, so the international federations returned to put their eye on their qualities. The breed was officially recognized in 2019.
