At a glanceThe Koolie Club of Australia records different ancestry and breeding-status situations through studbook sections. A section is an administrative description, not a ranking of an individual dog’s working value.WORKING DOG reference library · Added 2026-10-19 · Editorial guideKey factsSectionsA, B, C and P [source]Colour criterionColour and eye colour are not acceptance criteria [source]Section POffspring cannot be registered from that record [source]A register designed to record an existing populationThe club’s registration notes provide sections A, B, C and P. Section A requires parents already in A or B and a registered prefix. Section B accommodates specified cases involving unregistered ancestry and requires supporting evidence; adult applications include a side photograph. Section C records related working-dog ancestry with strong Koolie influence. These categories make the history behind a certificate important: the presence of a record need not mean every ancestor entered through the same documentary route. The registrar considers applications rather than accepting them automatically.Pet registration is a distinct restrictionSection P is for dogs registered as pets, with offspring ineligible for registration from that record. The notes nevertheless provide a certificate with pedigree details. Therefore, the existence of a pedigree and permission to register descendants are separate questions. The club’s public registration page should be read alongside the detailed notes when preparing an application. For a purchaser, the useful record is the actual section and conditions, recorded before a transaction, rather than an assumption based on whether a dog will live on a farm or in a household.Photographs and names have limited evidential rolesThe notes expressly exclude colour, eye colour and coat pattern as acceptance criteria. A photograph requested as supporting evidence is consequently not a substitute for a complete ancestry record. The document also explains state and section elements in registration numbers and distinguishes historical ancestors from dogs known to be registered. When digitising an old certificate, retain those original identifiers and any unknown ancestry. Filling blank generations with guessed Koolie names would destroy the very distinction the section system is intended to preserve. Confirm current procedures directly because an archived fee schedule is not a current quotation.Common questionsDoes Section B mean a dog is a poorer worker than Section A?The sections describe registration circumstances. They do not award comparative working-performance grades.Sources & further readingReferences for this guide.
