What matters most
Especially with a Prague Ratter, choosing the right breeder is the single most important decision you'll make. Serious breeders consistently test the parents for inherited conditions, prioritize healthy early socialization, and stay accountable long after handover. A cheap puppy without health screening tends to become the most expensive dog later on.
See HonestDog breeder standards →Is the Prague Ratter right for you?
The Prager Rattler is a lightning-fast, highly intelligent miniature ratter—originally bred to keep Bohemian farms free of rodents. Don't let his three kilos fool you: beneath that delicate frame beats the courageous heart of a true working dog.
Perfect for you if:
- You are looking for a tiny companion that you can still challenge like a big dog—this little hunter loves scent work or trick training.
- You have time for active walks in nature where he can burn off his nimble energy, rather than just walking around the block.
- You appreciate a dog that forms an extremely close bond with its owner and prefers to keep its distance from strangers at first.
- You lead with love but consistency, because even a dog of this size needs clear rules to prevent him from becoming a stressed-out control freak.
Less ideal if:
- You expect a passive lap dog—his heritage as a ratter means he reacts to movement stimuli in a flash and has a strong prey drive.
- You live in a building with thin walls—he is vigilant and will quickly announce unusual noises at the door with a high-pitched bark.
- You have very small, boisterous children at home who cannot yet respect the physical boundaries of this delicate but strong-willed dog.
The real vibes check
A Prager Rattler is not a handbag accessory—he is a sports car in the size of a Matchbox toy. If you treat him like a full-fledged dog, you get an untiring, brave partner; if you treat him like a toy, he will become nervous and yappy. He wants to conquer the world, preferably right by your side.
Breed Profile

History

It was only in the 1980s that Czech breeders began to systematically breed the Prague Rattler again, and since 1990 it has been officially recognized as a separate breed.

What owners say about the Prague Ratter
Sonja S., Halterin aus Bayern (Hündin, 7 Jahre alt)
Meine siebenjährige Hündin ist ein absolutes Energiebündel und unglaublich intelligent. Sie lernt im Handumdrehen neue Tricks und kann sogar Personen und Gegenstände namentlich zuordnen. Manchmal grinst sie mich richtig frech an und zeigt dabei ihre Zähne, wenn sie sich freut. Sie ist extrem sensibel und treu, aber man darf ihren eigenen Kopf nicht unterschätzen.
Klassische Unterordnung oder Dinge, die ihr schlichtweg keinen Sinn ergeben, stoßen bei ihr schnell auf Granit. Besonders bei Kälte und Regen verweigert sie gerne mal den Dienst – sie ist eben extrem wärmeliebend und friert schnell. Draußen ist sie mutig, manchmal fast schon übermütig gegenüber größeren Hunden, weshalb man da gut aufpassen muss. Trotzdem möchte ich diesen tollen Seelentröster nie wieder missen.
Laura M., Halterin aus Nordrhein-Westfalen (Rüde, 5 Jahre alt)
Unser fünfjähriger Rüde ist ein toller Begleiter, aber er fordert uns täglich heraus. Er ist extrem kommunikativ und kommentiert quasi alles: Wenn wir beim Gassigehen kurz stehen bleiben, fängt er sofort an zu fiepen. Wenn sein Deckchen aus dem Körbchen rutscht, steht er davor und jammert. Und wenn man ihn mal tadelt, fängt er regelrecht an, lautstark mit uns zu 'diskutieren' und zu brüllen – ignorieren hilft da leider gar nicht.
Eine weitere große Baustelle ist das Alleinebleiben. Sobald wir die Wohnung verlassen, fängt er an, jämmerlich und so laut zu jaulen, dass man es bis auf die Straße hört. Trotzdem ist er kein verhätscheltes Schoßhündchen, sondern darf alles auf 'Hunde-Art' machen und beherrscht seine Grundkommandos eigentlich super. Er ist unheimlich lieb und aufgeschlossen, aber seine Anhänglichkeit und das Mitteilungsbedürfnis verlangen uns viel Geduld ab.
Steffi B., Halterin aus Hessen (Hündin, seit 2010)
Vor der Anschaffung hatte ich große Bedenken wegen der Gesundheit der Rasse, da man oft von Problemen mit zu kleinen Kiefern und Zähnen liest, die gezogen werden müssen. Zum Glück haben wir einen gesunden Hund erwischt. Unsere Hündin ist extrem menschenbezogen, sportlich und lässt sich super für Agility begeistern. Sie ist aber auch sehr wachsam und Fremden gegenüber erst einmal misstrauisch.
Was man bei dieser Rasse wissen muss: Sie brauchen unbedingt den Kontakt zu anderen Hunden. Unsere Hündin liebt das 'Kontaktliegen' mit ihren Artgenossen und blüht in der Gruppe richtig auf. Sie ist zwar winzig, aber ein absolut vollwertiger, aktiver Hund mit einem riesigen Herzen, der gefordert werden will.
