As demand for French and English bulldogs, pugs, and other flat-faced pets increases, so too do the life-threatening respiratory ailments that afflict these breeds. Dr. Heidi Phillips, a professor of veterinary clinical medicine at the University of Illinois Urbana-Champaign, uses surgical approaches to open up the airways of flat-faced dogs and cats that struggle to breathe. Here, she describes her work to improve the respiratory function of these animals and talks about adopting better breeding practices to prevent the problems associated with Brachycephalic Obstructive Airway Syndrome in dogs and cats.
