Abstract
Background
Brachycephalic dog breeds often exhibit a suite of extreme conformations linked with several severe and long-term disorders. Despite this, ownership levels of brachycephalic breeds remain high internationally, with physical appearance being an important driver in their acquisition. Moving these breeds away from conformational extremes is necessary to protect canine welfare. This study aimed to explore how a range of extreme conformations in common brachycephalic breeds are perceived by the UK public.
Methods
An online questionnaire used images generated by artificial intelligence of typical, less extreme and super extreme versions of three common brachycephalic breeds (French Bulldog, Pug and English Bulldog) to assess preferences among the UK general public for varying degrees of conformational extremes of muzzle length, eye size/shape, skin wrinkling and tail length.
Results
The survey included results from 4899 participants. The less extreme versions of all three breeds were rated significantly higher by the public, including owners of purebred brachycephalic dogs, for attractiveness, perceived health, how happy they made the participant feel, ethics of breeding and how much the participant would like to own that dog (p < 0.001).
Limitations
The participants were UK-based only and largely female, restricting generalisability.
Conclusion
If given a choice, the UK public prefers less extreme body shapes in brachycephalic dog breeds. This presents major welfare opportunities to reverse the current normalisation of extreme body shapes in some currently popular brachycephalic dog breeds.
