Symptoms and treatment of tracheal collapse in dogs.

Symptoms and treatment of tracheal collapse in dogs.

Overview

The trachea can be divided into the neck trachea and the trachea in the chest cavity. The trachea stenosis caused by abnormal structure or external factors (such as tumor) in any part of the trachea is collectively called tracheal collapse. It is more likely to happen to small dogs, such as Pomeranian, Chihuahua and Maltese breeds.

Causes

A study showed that the collapse of the dog’s trachea was due to the lack of chondroitin sulfate in the canine’s tracheal ring. Cushing’s disease (hyperadrenal glands) can cause a weakening of the cartilage structure of the trachea. There is evidence that more than 50% of the tracheal collapse is due to the gradual weakness of the tracheal cartilage, and the trachea continues to collapse.

The main symptoms

1. Coughing will become severe due to the hot weather, excitement, and exercise;

2. May faint due to hypoxia;

3. Exercise intolerance.

Diagnostic criteria

1. Chest X-ray: When shooting, it is divided into two methods: inhalation and exhalation. Inhalation: When inhaling, it is easier to diagnose the collapse of the neck trachea. Exhalation: When exhaling, it is easier to diagnose the collapse of the trachea in the chest cavity.

2. Tracheal irrigation: endoscopic and cytological examination of the trachea can further understand the possible causes.

Treatment method

A tracheal dilator can be used. In severe cases, surgery is required to rebuild the trachea. Long-term tracheal collapse can easily cause heart disease, so regular heart examinations should be performed. Pet owners should learn cardiopulmonary resuscitation and be prepared to carry bottled oxygen in case they need it.
