Tracheal Collapse in Dogs. Stenting of the Trachea

Tracheal collapse is a chronic degenerative disease that manifests itself by deforming the tracheal rings. The trachea is flattened from top to bottom, losing its rigidity, as a result of which the lumen takes the shape of the letter “C”.

This leads to the fact that the upper and lower walls of the trachea constantly touch, the dog begins to cough. The cough may be so severe that it may be fatal as a result of suffocation. It is worth noting that the collapse of the trachea develops, as a rule, in dogs of small breeds.

Diagnostic methods

It is possible to predict the development of tracheal collapse even in the absence of clinical manifestations. To do this, you need to palpate the trachea and evaluate its shape. Reliable evidence of the development of the disease is the presence of any flattening or grooves on the lower wall.

The cough that appears is the main symptom of the development of the disease. Initially, it may be short — lived-after running or playing. However, with the development of tracheal collapse, the cough becomes more frequent and may be present all the time.

Breathing becomes difficult, wheezing occurs, and the tongue becomes purple. If you do not contact the veterinary clinic in time, the animal may suffocate and die.

The disease is diagnosed on the basis of an initial examination and an x-ray. In addition, it must be confirmed by endoscopic examination, which allows you to determine the stage of the disease. The stage of collapse is directly dependent on how seriously the trachea is flattened.


Tracheal collapse is a genetic disease, so it is almost impossible to get rid of it. However, medicine does not stand still, and with it our veterinary clinic. We are moving forward, finding new solutions to known problems. In particular, stenting in case of collapse is one of the most effective ways to restore the tracheal lumen and prolong the life of the animal.

Stenting is a method of restoring the trachea that does not require surgery. The lumen is restored by installing a special stent, which has a cellular cylindrical structure and is made of nitinol. Nitinol is a special metal that can “remember” shapes. The stent acts as a framework that supports the collapsed tracheal region. It should be selected individually for each dog, depending on the diameter of the trachea and the length of the sleeping gap.

The advantages of this method can also be appreciated by clients of the clinic»:

  1. Instant recovery of the sleeping area: the stent opens within a few seconds. The dog’s breathing becomes even, the wheezing disappears.
  2. Stent implantation takes about a month. It becomes a full-fledged frame of the trachea.
  3. It is one of the most effective methods of tracheal restoration. Allows you to save a dog’s life in a few seconds and extend it for several years.

Prevention methods

First of all, you need to give up the collar and use a harness. The fact is that any jerk or sharp impact on the neck can cause a cough, which occurs as a result of irritation of the trachea and can cause the development of collapse.

In addition, you need to regularly deal with the prevention of diseases of the upper respiratory tract, such as pneumonia, laryngitis, bronchitis, rhinitis. It is necessary to carry out vaccination in time, avoid drafts and regularly ventilate the room where the dog is located. It is also worth noting the importance of maintaining a normal Constitution, since obesity is one of the factors that contribute to the development of tracheal collapse.
