Our dogs

We have six of these beautiful little dogs and would like you to know a little more about the breed. We have spent many months researching the breed and contacting breeders before going to the Czech Republic to bring home first Abi (black and tan girl) in July 2012, then Bruno (red boy) in October 2012 They were joined by three black and tan short-hairs – two girls; Ceska in September 2013 and Zara in September 2015 and a boy; Maxi, in November 2015. You can see further details of these lovely dogs on our Dogs page.

We know of around a dozen P.K.’s living in Britain and Ireland but – as far as we know – our two and their offspring are the only longhaired PKs over here. If you have a Prazsky Krysarik, we would love to hear from you.

About the breed

The Prazsky Krysarik (Prague Ratter) is a tiny breed of dog from the Czech Republic that is rarely seen outside its country of origin. It is the smallest breed in the world by breed standard, because of the maximum height of the dogs, unlike Chihuahuas who are measured by weight.

Often confused with the Chihuahua and the Miniature Pinscher, it is 2 cm shorter in maximum height than the minimum height of the Miniature Pinscher. The ideal height is 20 cm to 23 cm. Adult weight is mostly between 1,5 kg to 3,5 kg. Generally the best weight is 2,6 kg. 


Type of hair: 1) Short, shiny, tight, dense not bald. On the head the hair is usually thinner and shorter than the body. 2) Medium long, flags on ears, legs, tail and slightly on the chest.  The most common colour is black and tan, which is also the original colour. Lately, other colours have been approved: Brown and tan, Blue and tan, Lilac and tan, Yellow, Red and Merle. 


Best known for its active and lively nature, the Prague Ratter is a spunky breed that is full of original character. These tiny dogs thrive on strong and dependable relationships with humans, love to receive affection and play the role of lap dog during down time. To his owners and family members the PK is friendly and affectionate. They can be suspicious and aloof with strangers .This breed is highly intelligent and generally responds well to training .

As a pet, the Prague Ratter is obedient, loyal, loving, and very affectionate. The Prague Ratter adapts well to full-time indoor and apartment living, yet still enjoys spending time outdoors, playing games such as fetch, taking long walks and racing around, given the opportunity.


Due to its need for human attention and eagerness to please and impress its owner, the Prague Ratter generally responds well to basic training and commands. This bright breed has the ability to learn to perform many impressive tricks and tasks.
