Which dog breed is commonly associated with congenital tracheal hypoplasia?

• A. English bulldog
• B. Beagle
• C. Pug
• D. Chihuahua

Answer: (A)

Congenital tracheal hypoplasia is a birth condition where the trachea is underdeveloped, producing a narrowed airway that can cause coughing, wheezing, and exercise intolerance. It is especially common in brachycephalic breeds, whose short skull and altered airway development predispose them to tracheal and other airway abnormalities. The English bulldog is a classic example in veterinary teaching because its extreme brachycephalic conformation frequently comes with a hypoplastic trachea, making this association widely recognized. In clinical practice, you might see noisy inspiration and coughing, and radiographs often show a tracheal diameter that is small for the size of the thorax. While other small brachycephalic breeds (like pug or Chihuahua) can have tracheal hypoplasia, the bulldog is particularly noted for this congenital airway issue.
