What the Standard Said Before, and What It Says Now

Where the Language Changed

The Kennel Club's 2009 review of breed standards, conducted in the wake of the 2008 Pedigree Dogs Exposed broadcast and the Bateson review it prompted, produced amended standards for more than two hundred breeds. For the flat-faced breeds, the revisions were substantive. The bulldog standard, which had described a head "very large" in proportion with no qualification about respiratory function, gained a new clause requiring that the dog "should be able to breathe freely with no indication of breathing difficulty." The French bulldog standard was similarly amended; language that had previously celebrated extreme skull compression was offset by a welfare sentence affirming that any "respiratory distress" must constitute a fault. The pug's standard acquired comparable wording.

The mechanism of change was direct: the Kennel Club issued updated standards, effective from 2009, and required that judges penalise visible breathing impairment as a fault at licensed shows. The stated aim, as the Kennel Club documented in its published guidance at the time, was to ensure that the standard could not be read as endorsing a conformation whose functional consequences were harmful.

What the revised language did not do was metrically define the level of intervention. There is no muzzle-length minimum in the KC standards, no skull-index ceiling, no requirement that dogs be graded before exhibition. That more prescriptive approach was taken later, and separately — the Respiratory Function Grading Scheme developed jointly by the Kennel Club and the University of Cambridge introduced the four-point scale assigning Grades 0 to 3 after a standardised exercise test, but participation remained a requirement only for certain health schemes rather than a universal condition of registration or entry.

How the FCI Text Compares

The Fédération Cynologique Internationale, which coordinates breed standards across more than ninety member countries and maintains its own standard documents, has not moved in lockstep with the Kennel Club revisions. The KC holds the role of standard-setter of record for British breeds under FCI arrangements, which means FCI members are formally bound by the KC text for breeds of British origin. In practice, the FCI standards for the bulldog, French bulldog and pug — classified under FCI Group 9 for the French bulldog and Group 2 for the bulldog — reflect the updated KC language where the KC is the country of origin and custodian. The welfare sentences introduced in 2009 therefore appear in those FCI-adopted texts.

Where the divergence is visible is in breeds whose country of origin is not the United Kingdom. For such breeds — the Pekingese, for instance, falls under KC registration but with a standard the FCI holds independently — the alignment is less automatic. Comparative evidence published by researchers including Rowena Packer at the Royal Veterinary College has consistently shown that standard language specifying preferred skull morphology continues to drive selection toward shorter muzzles regardless of welfare clauses, precisely because those clauses are subjective while the conformation descriptions are graphic.

The Norwegian and Dutch interventions subsequently went further than any standard revision: the Borgarting Court of Appeal in 2023 found that breeding English bulldogs and cavalier King Charles spaniels caused suffering under Norwegian animal-welfare law, while the Netherlands established a measurable muzzle-length rule in 2019. Neither instrument is a breed standard; both operate outside the kennel-club standard framework entirely.

The 2009 KC revisions remain the last general revision of brachycephalic-breed language within the UK standard system. The text now says that breathing difficulty is a fault. Whether judges, breeders and registrations have responded accordingly is a question the welfare literature has continued to answer — with consistent scepticism.
