History of Prague Ratter

The first written mentions of the Prague Ratter come from the 8th century. The breed enjoyed a great popularity at the court where puppies were often given as valuable presents and signs of peace, as well as in common households where they were bred to kill rats. Ratters were often present at important feasts at the Prague Castle.

Later on the Prague Ratter became a companion of burghers who had no more need for a ratter but a companion dog was a part of their social status.

Although the breed is not internationally recognized and not very common beyond the borders of the Czech Republic, it was awarded provisional recognition by the FCI in April of 2019 and you can see the breed at Czech and Slovak dog shows.
