What Prevents The Trachea From Collapsing: Factors

Dogs are known for their adorable floppy ears, but what many people don’t know is that those floppy ears play an important role in helping keep the trachea from collapsing.

In this post, we’ll take a closer look at What Prevents The Trachea From Collapsing and why it’s so important. We’ll also discuss some of the most common causes of tracheal collapse in dogs. So if you’re a dog lover, be sure to read on!

What Is Trachea In Dogs:

The trachea, or windpipe, is a tube that runs from the throat to the lungs. It’s responsible for transporting air in and out of the body, and it’s also one of the main areas where dogs can catch infections.

Which Factor Prevents Trachea From Collapsing:

There are a few different factors that work together to prevent the trachea from collapsing. These include:

1. The Cartilage:

As we mentioned, the cartilage plays an important role in keeping the trachea open. It’s flexible and strong, and it helps to support the airway.

2. The Muscles:

The muscles surrounding the trachea also help to keep it open. The contract is when the dog breathes in, and this helps to suck air into the lungs.

3. The Mucous:

The mucous that coats the inside of the trachea helps to keep it moist and lubricated. This prevents it from becoming dry and stiff, which would make it more likely to collapse.

Why Does Tracheal Collapse Occur In Dogs?

There are a number of reasons why the trachea can collapse in dogs. Some of the most common causes include:

1. Infections:

Infections of the respiratory system are one of the most common causes of tracheal collapse in dogs.

2. Allergies:

Allergies can cause inflammation and swelling of the airways, which can lead to tracheal collapse.

3. Smoke Inhalation:

Smoke inhalation can irritate and damage the trachea, leading to collapse.

4. Foreign Objects:

If a dog swallows a foreign object, it can get lodged in the trachea and cause it to collapse.

5. Tracheal Tumors:

Tumors of the trachea can lead to inflammation and obstruction, which can cause the trachea to collapse.

How To Prevent Trachea From Collapsing:

There are a few things that you can do to help prevent your dog from experiencing tracheal collapse. Some of the most important include:

1. Keep Your Dog’s Vaccinations Up To Date:

Vaccinations can help protect your dog from respiratory infections, which are one of the main causes of tracheal collapse.

2. Keep Your Dog Free Of Parasites:

Parasites can cause inflammation and irritation of the airways, leading to tracheal collapse.

3. Keep Your Dog Away From Cigarette Smoke:

Cigarette smoke can irritate and damage the trachea, leading to collapse.

How Is Tracheal Collapse Treated?

If your dog is diagnosed with tracheal collapse, there are a number of treatment options available. Treatment will depend on the cause of the collapse, and may include:

1. Antibiotics:

if the trachea collapse is caused by an infection, antibiotics will be prescribed to clear up the infection.

2. Steroids:

If the collapse is caused by allergies, steroids may be prescribed to reduce inflammation and swelling.

3. Surgery:

In some cases, surgery may be necessary to correct the cause of the tracheal collapse.

4. Cough Suppressants:

If the dog is coughing due to the collapse, cough suppressants may be prescribed to help stop the coughing.

5. Bronchodilators:

Bronchodilators can help open up the airways and make it easier for the dog to breathe.

Potential Side Effect Of Trachea Collapse:

There are a few potential side effects of tracheal collapse, including:

1. Respiratory Infection:

If the trachea collapses, it can lead to an accumulation of mucus in the airways. This can increase the dog’s risk of respiratory infection.

2. Difficulty Breathing:

If the trachea is partially or completely blocked, the dog will have difficulty breathing.

3. Coughing:

The dog may start coughing as a result of the tracheal collapse.

4. Stridor:

Stridor is a high-pitched noise that is caused by restricted airflow through the trachea. It can be a sign of tracheal collapse.

5. Swelling:

The dog’s neck may swell as a result of the tracheal collapse.


The trachea is a cartilaginous tube that connects the larynx with the bronchi and lungs. It keeps airways open so that oxygen can be inhaled and carbon dioxide exhaled.

The main component of the tracheal wall is cartilage, which prevents the trachea from collapsing. There are several layers to the tracheal wall including mucous membranes, connective tissue, and muscles.


1. What is the anatomy of the trachea and why doesn’t it collapse?

Answer: The trachea is a tube that connects the lungs to the larynx and carries air into and out of the lungs. It is made up of several C-shaped cartilage rings that keep it open and prevent it from collapsing.  

2. How do dogs breathe and what prevents their tracheas from collapsing?

Answer: Dogs are special creatures, not just because they’re our best friends, but because of the way they’re built. Unlike humans, who have a soft cartilage skeleton. 

3. What are some common medical conditions that can affect a dog’s trachea?

Answer: Common medical conditions that can affect a dog’s trachea include allergies, infection, and injuries. Allergies are the most common cause of trachea problems in dogs. They can be allergic to pollen, mold, dust, and dander. 

4. How can you tell if your dog is having trouble breathing?

Answer: The first and most important sign that your dog is having trouble breathing is an increase in their respiratory rate. A rough guide to how many breaths per minute a healthy dog should take is 20-40, and anything over 60 is too high.

5. What are the treatments available for dogs with collapsed tracheas?

Answer: The first line of treatment for a collapsed trachea is typically medical management. This means working with your veterinarian to come up with a plan that will help ease your dog’s breathing symptoms.
