FCI standard 363
Prague Ratter.
FCI 363: companion dog (Group 9 Companions and Toy Dogs). FCI history: kept at the courts of Bohemian kings and nobility and used for killing rats. Wikipedia: used as rat catchers in rural and urban households; takes part in agility, obedience and tracking today..
Breed sets the odds. The parents set the dog. Every number here shows its source, its spread and how sure we are. Nothing on this page is a prediction about one dog.
The body
What the breed is built like. Registry standards give an ideal, not a range.
Height at the shoulder
One breed-wide range counted in both sexes (the standard gives the same figure for males and females). Low is 20 cm (7.9 in), the bottom of the FCI tolerance and Wikipedia; high is 24 cm (9.4 in), the top of the FCI tolerance. The FCI prints a range, not a single ideal, so center is blank. The club's own measurements show the population sitting at the top of the standard and above it; shown, not averaged.
Weight
Center is the FCI ideal, 2.60 kg = 5.7 lb (conversion stated). Low and high are Wikipedia's editorial range, 1.5 kg = 3.3 lb to 3.5 kg = 7.7 lb, the only printed range; the FCI prints no minimum or maximum.
Coat
Two coat varieties of one breed in the FCI standard and Wikipedia.
Heat tolerance
Derived from coat. A short single coat sits at 5; the fringed variety and the tiny fine-boned frame hold it at 4 as a flagged judgement. No heat-illness study was opened.
The dog at home
What the breed asks of a day. The first thing most homes get wrong.
Exercise need
Editorial only. No registry or club source read gives minutes, so exercise_need_min is left out.
The work
What it was built to do in the field, and what a test or trial asks of it.
Role
A companion breed today; the ratting is history.
Primary game
History and instinct, not a current use.
Field trial standard
No field test applies.
How common the problems are
Evaluated dogs skew toward breeding stock; the numbers are still the best there are.
Most common disorders
Breeding-stock statistics from the breed club's own assessments, not a random sample of pet dogs. Wikipedia's health section carries a verification-needed tag; the club figures stand on their own. No VetCompass study was read.
What to ask a breeder for
The health clearances the breed’s own club and registry name. Reference only: what to ask for, never a statement about any dog’s health.

How to read this page
Every value carries a label. Measured means peer-reviewed data on many dogs. Studied means peer-reviewed, smaller or indirect. Breed club means a club or registry states it. Editorial means expert opinion with no measurement behind it. Where two good sources disagree, both are shown and neither is averaged.
Published when the entry rests on the best information available from no fewer than three independent sources, checked by a second pass that did not write it. 4 sources on this page. Found something wrong? Tell us and the correction is logged with its date.
