Tracheal Collapse (Collapsing Trachea)

Section: Overview

Tracheal collapse is a commonly encountered cause of airway obstruction and coughing in the dog. The cause remains unknown, although there may be many factors involved. The most likely cause is abnormal synthesis of the cartilage that is part of the structure of the trachea. The disease causes dogs to cough in spasms.

Either sex may be affected, although it is almost always a disease of toy breeds. Yorkshire terriers are the most commonly affected, but Pomeranians, Chihuahuas, poodles and Maltese are also predisposed. It may affect dogs of any age, although the average age at which clinical signs first appear is six or seven years.

What to Watch For

Tracheal reconstruction is sometimes recommended.

Home Care and Prevention

Administer medication as prescribed. Use a harness instead of a collar and treat any concurrent conditions that might exacerbate the tracheal collapse. Isolate or remove the dog from any potentially irritating substances such as cigarette smoke or excessive dust.
