In terms of appearance, krasiks resemble pinschers, chihuahuas, toy terriers, and certain other small dogs. Despite having distinct qualities, they have not yet received official recognition. Prague Ratters can be distinguished from representatives of other breeds by looking at the photo.
- Most often, Prague Ratters are confused with Toy Terriers. At first glance, the difference is really not visible: they are similar in body structure and muzzle, color, ear placement. But Toy Terriers are larger in size and body weight, the build is more elongated and lean, and the ears are not as wide at the base.

- There is a difference between the Prague Ratter and the Russian Toy. The Ratter has a more miniature, but muscular build. The Russian Toy has a sloping back, large, slightly convex eyes, a shorter muzzle with a sharp stop. And the character, unlike the Prague Ratters, is more consistent with indoor dogs.

- The difference with the Chihuahua is more clearly visible, although in size these are the two smallest breeds in the world. Raters are slightly taller, have an elegant build. Chihuahuas have a shorter muzzle, large, wide-set and bulging eyes, a wide forehead and a wide variety of colors.

- The krysariks are related to the pinschers, but despite this, they are very different in appearance. Zwergpinschers are larger, heavier, with a strong build. The muzzle is narrower, the fur is hard, the ears can be semi-erect. Only in character and behavior are there almost no differences.

Prague krysariks: history of the breed
The Prague krysariks are the oldest dog breed in the Czech Republic, according to numerous researchers. It was well-known even when it was first mentioned in the eighth century. These tiny dogs resided in numerous aristocratic homes and royal chambers. There is some variation that claims they are descended from pinschers, but nothing is known about the breed’s historical origins.
These dogs enjoyed great popularity in the Middle Ages, particularly in the homes of the aristocracy. Kings from several European nations received puppies. Ratliks were permitted to browse around tables and sample food in order to ensure it was safe. But removing mice and rats from palaces was their primary responsibility. There was no way to avoid rodents back then, and cats were not kept because the church believed they were spirits’ servants.
The Czech Republic was in decline by the 17th century, and no longer did aristocrats own little dogs. The impoverished came to love krysariks because they kept rodents out of their homes. However, the breed’s population had significantly declined by the end of the 19th century. Two world wars had an impact on it as well. It wasn’t until the 1970s that enthusiasts started to bring it back to life.
Jan Findeis and Rudolf Schiller, cynologists, created the Prague Ratter breed standard. Even though it’s still uncommon, many cynological clubs now recognize it. It is primarily found in Slovakia and the Czech Republic. The FCI designated the breed as a group of decorative dogs in 2019 and granted it provisional recognition.
