How to distinguish reverse sneezing from collapsed trachea?
A chronic cough, especially a “goose honk,” should be suspected as having collapsed trachea. Many times, very light pressure placed on the trachea during the physical examination can raise a suspicion of collapsed trachea in a Maltese with a persistent dry cough. While the information gained from the physical examination is helpful, other tests are needed to confirm this condition. Radiographs (x-rays) of the chest can identify the trachea and its shape. However, a collapsed trachea changes its diameter during the respiratory cycle. It is usually collapsed during inhalation and normal during exhalation. Therefore, an attempt to make radiographs during both phases of respiration in necessary. This can be rather difficult to accomplish since dogs are not likely to understand the command, “Take a deep breath and hold it.” Endoscopy is another way to evaluate the trachea. An endoscope is a tube that is small enough to insert into the trachea; the operator can see through it and visualize t
