Collapsing Trachea

General Information:

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 air flow in and out of the lungs.

This condition is commonly found in small breeds of dogs like Chihuahuas and Pomeranians.

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 Tracheobronchitis (Kennel Cough).

Treatment Information:

A complete physical examination and radiographs (x-rays) are usually 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 the pet's lifestyle 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.
