How breed standards work
A breed standard is a written description of the ideal specimen. Every judgement in the ring traces back to one.

No dog has ever fully met its standard. That is the point of having one — it is a direction, not a threshold.
Who writes them
A standard is written and maintained in the breed’s country of origin, then adopted by registries elsewhere. That is why the definitive standard for the German Shepherd is German, for the Shih Tzu is Chinese by way of Britain, and for the Jack Russell is British. The JKC adopts recognised standards rather than writing its own — which is precisely what makes a JKC pedigree portable when a dog is exported.
What a standard contains
- General appearance and proportion — the overall shape, and the ratios that define it
- Head, eyes, ears, bite — usually the most detailed section, and where breed type lives
- Body, forequarters, hindquarters — the construction that determines movement
- Coat and colour — including which colours are disqualifying
- Gait — how the breed should move, which is where construction is proven
- Temperament — and in the breeds where it matters most, this section outranks all the others
Why standards differ between registries
Different registries adopt different revisions, and occasionally disagree outright about size, colour or coat. This is ordinary, and it is why the registry that issued a pedigree matters as much as the pedigree itself.
What a standard is not
It is not a health guarantee, and it is not a licence to breed for exaggeration. Where a standard’s literal reading would produce a dog that cannot breathe, whelp or move comfortably, the club sides with the dog. Judges are instructed to reward soundness over extremity, and breeders will find that the register is where that instruction has consequences.
