About the Prague Ratter
The Prague Ratter (Prazsky Krysarik) is a tiny, elegant toy breed from the Czech Republic, often cited as one of the smallest dogs in the world. Historically kept in Bohemian courts and homes as a companion and capable rat-catcher, it combines a delicate, deer-like build with a surprisingly lively, alert, and courageous character. Its smooth coat is typically black-and-tan, though other colors occur. Affectionate and closely bonded to its people, the Prague Ratter is playful and trainable but can be wary of strangers and sensitive to cold. Its small size suits apartment living, yet it retains a genuine terrier-like drive and enjoys games and gentle activity.
Every dog is an individual — genetics, socialization, health, training, and environment matter more than breed averages.

The breed declined for centuries and was reconstructed by Czech enthusiasts in the late 20th century. It is recognized nationally in the Czech Republic and is gaining wider recognition, though it is not yet FCI-registered.
