The Prague Ratter (also named Prague Ratter or Pražský krysařík) is a small dog breed rarely found outside of Czechia, its country of origin. It is the smallest dog breed in the world according to statistics (compared to the maximum size of the dog, unlike the Chihuahua which is measured by weight). It is often confused with the Miniature Pinscher, a breed with a similar physique to the Prague Ratter.

Getting to know the Prague Ratter
Origins & history
A story told
Although the Prague Ratter is mainly known as a pet, it was originally created with the objective of replacing cats in the hunting of pests (rats, voles...). King Boleslaus I of Poland (1058–1080) owned two Prague Ratters originating from Bohemia. Then this dog became less popular during the 20th century in favor of the Miniature Pinscher (with which it is often confused). Nevertheless, this breed is beginning to thrive again with the increase of Czech and Slovak breeders who breed them.
