Bhe-Jei Maltese

Collapsing Trachea

The trachea (windpipe) is composed of 35-45 C-shaped rings of cartilage that are joined by muscle and ligaments to create a tube-like structure. Certain conditions can result in the trachea's losing its tube-like shape so that it collapses much like a soda straw being drawn on too vigorously. When the trachea collapses, air can no longer move freely through it. Then the animal breathes with difficulty and exhibits a honking cough.

Causes include trauma to the windpipe, nerve damage, inherited tracheal weakness, degeneration of cartilage and abnormal airflow in and out of the lungs. This condition is commonly found in small breeds of dogs including Maltese. Except for the congenital (present at birth) forms of tracheal collapse, most cases occur in middle-aged or older, overweight, small-breed dogs. This condition closely resembles Kennel Cough.

If your Maltese has any of the symptoms of collapsing trachea your should visit your veterinarian. He should perform a complete physical examination. Radiographs (x-rays) are many times necessary to confirm a diagnosis of tracheal collapse.

Depending on the severity of the condition, treatment may include surgery and/or medical therapy. In mild cases, a change in lifestyle of your Maltese may be all that is necessary. Some cases of collapsing trachea cannot be cured, and treatment is directed at decreasing the severity and frequency of breathing difficulties.
