The severity of Brachycephalic Obstructive Airway Syndrome (BOAS) is assessed by means of walk tests. With the help of walk tests, individuals with the most severe symptoms can be eliminated from breeding.
A thought-provoking video that highlights the challenges of brachycephalic breeds - from educating breeders, to the veterinarians who are inevitably called upon to treat dogs bred for exaggerated characteristics.
Australian Veterinary Association - Specialist surgeon, Adjunct Professor Philip Moses, provides some words of advice for the veterinary profession about how to best tackle the welfare problems of dogs with exaggerated features.
"More information: https://www.vet.cam.ac.uk/boas/about-... The French bulldog, bulldog, pug, pekingese, shih tzu, Japanese chin, boxer and Boston terrier are all examples of brachycephalic breeds. The most distinctive feature of these breeds is their short muzzle. Brachycephalic dogs have been bred for centuries to possess a normal-sized lower jaw, and a disproportionately shorter upper jaw.
In recent decades, breeding selection for extreme brachycephalic features has resulted in dogs that are predisposed to upper airway tract obstruction and subsequent respiratory distress, among several other health issues. Although not all brachycephalic dogs suffer clinical signs, the incidence and severity of the respiratory disorders has increased. The respiratory disease related to brachycephalic confirmation is called brachycephalic obstructive airway syndrome (BOAS)."
Making Assessments of Dogs' Respiration has been produced by the Swedish Kennel Club as part of the work in improving health in pedigree dogs. The film illustrates the causes and background to dogs' respiratory problems and the difficulties to adjust the body temperature. The film discusses the signs of affected breathing that a judge may observe. (English subtitled)
Making Assessments of Dogs' Respiration is a complement to the Breed-Specific Instructions for Judges, BSI.
