Tracheal collapse in dogs is a grave condition prevalent in small dog breeds. This usually occurs when the cartilage rings that support the trachea become weak, therefore causing the trachea to flatten. 

When this happens, significant breathing difficulties may occur, making it crucial to understand its clinical signs and potential causes. This is so you can conduct a timely intervention and management before it turns into a painful ordeal for your dog. 

In today’s post, you’ll learn valuable insights on how to safeguard your dog’s health and well-being by reading the causes, symptoms, and treatment options for tracheal collapse. Keep reading to explore this important topic in detail. 

What Is a Trachea?

The trachea, also known as the windpipe, is a vital part of a dog’s respiratory system. It is a tube connecting the throat to the lungs, allowing air to flow smoothly during breathing.

Its structure is maintained by small C-shaped cartilage rings along its tracheal wall. The number of these rings varies from 36 to 45, and they keep the airway open and maintain the trachea’s tube-like, near-circular shape. In dogs, these rings cover around 83% of the circumference. What completes the circle is a thin tissue membrane. 

Additionally, the overall form of the trachea varies in size at different levels, with the smallest diameter found at the thoracic inlet. This is where there’s a higher risk of tracheal collapse due to it having the thinnest cartilage among other sections of the trachea. 

What Is Collapsing Trachea in Dogs?

Collapsing trachea in dogs is a serious medical condition where the trachea becomes weak and collapses in varying degrees. In severe cases, the collapse may extend into the bronchi or the lower airway to the lungs. 

When such happens, the cartilage rings supporting the trachea lose their rigidity, causing the windpipe to flatten and narrow the airway. As tracheal collapse occurs, the condition restricts normal airflow and may lead to breathing difficulties. 

This is mostly common to toy and small breed dogs as their tracheal cartilage is more delicate. Moreover, they usually have higher respiratory rates due to their smaller lung size compared to larger dogs. 

The lower lung capacity is compensated through increased respiration, especially during exercise. This results in putting more pressure and strain on the trachea, contributing to its collapse over time. 

How Is Tracheal Collapse Diagnosed?

Tracheal collapse is diagnosed through clinical examination, history taking, and diagnostic imaging. This multi-faceted approach enables vets to accurately identify tracheal collapse, among other respiratory issues. Doing so ensures the right course of action to implement regarding treatment options. 

Clinical Examination

In this stage, your vet observes symptoms that indicate your dog is suffering from tracheal collapse. They may palpate the trachea to elicit a cough or listen to the airways and lungs using a stethoscope. 

History Taking

Your vet will ask about the onset, duration, and progression of the symptoms observed. Information about coughing episodes during excitement or exercise can be crucial. 

Diagnostic Imaging

Diagnostic imaging is the visualization of the internal structure of the dog’s body. This helps your vet accurately diagnose and monitor various conditions, specifically of the trachea.

Below are some of the techniques used for diagnostic imaging:

  • Radiography (x-rays): X-rays provide a static image of your dog’s trachea to help diagnose tracheal collapse. They also identify the location of the issue and severity of the condition. 
  • Fluoroscopy: Fluoroscopy is a real-time X-ray technique allowing for dynamic assessment of the trachea as your dog breathes, offering a clearer view of tracheal dynamics.
  • Tracheoscopy or bronchoscopy: Tracheoscopy is done by inserting a flexible camera, called an endoscope, into your dog’s trachea. This directly visualizes the tracheal walls and the extent of collapse. Meanwhile, if further inspection into the bronchi, the main airways leading into the lungs, is required, a bronchoscopy is conducted.
  • Computed Tomography (CT) scan: Your vet may opt for a CT scan for surgical planning or if other techniques are inconclusive. This procedure offers a more detailed, cross-sectional view of your dog’s trachea. 

Other Tests

There are also additional tests your vet may conduct as part of the comprehensive evaluation before ultimately ruling out that your dog suffers from tracheal collapse. 

This may include blood tests to assess if the symptoms point toward other underlying conditions or a heart evaluation since heart disease can cause similar symptoms as tracheal collapse, such as breathing difficulties, coughing, and exercise intolerance. 

Response to Treatment

In certain cases, the response to the treatment with cough suppressants, anti-inflammatory medications, or bronchodilators can support the vet’s diagnosis. 

Generally, if your dog shows improvement after receiving the initial treatment, it can provide additional evidence indicative of tracheal collapse. Still, it is not definitive proof of the condition. Other methods, like imaging, are still essential for a conclusive diagnosis. 

Causes of Tracheal Collapse in Dogs

The exact cause of tracheal collapse is unknown. Still, several factors are believed to contribute to the development of this condition.

Here’s a list of the factors of tracheal collapse in dogs:

  • Genetic predisposition: Collapsing trachea is prominent in small breed dogs, such as Chihuahuas, Yorkshire Terriers, and Pomeranians. Although there’s no research about how the condition is passed down or what genetic factors are involved, the frequency of the disease among small dogs suggests a hereditary component to the disease. 
  • Obesity: Excess weight can worsen tracheal collapse in dogs by putting extra pressure on the trachea, weakening its support structure. Fat deposits around the neck can also narrow the airway, making breathing more difficult.
  • Chronic respiratory conditions: Long-term respiratory problems, like chronic bronchitis, can also damage the trachea over time. If the tracheal rings, which keep the trachea open, are inflamed due to ongoing irritation and infection, the cartilage that makes up these rings becomes less rigid and may no longer properly support the windpipe.
  • Age: Collapsed trachea is a common health problem found specifically in middle-aged small breeds. This is because the cartilage that forms the tracheal rings degrades naturally as the dog ages. As it loses its elasticity and strength, the trachea becomes more susceptible to collapsing even under the pressure of normal breathing.
  • Environmental factors: Dogs exposed to smoke, airborne irritants, and pollution are also at risk of developing tracheal collapse. These airway irritants may cause inflammation or irritation of the respiratory tract and worsen existing respiratory conditions, eventually resulting in the weakening of the tracheal rings.
  • Harness or collar pressure: Harnesses and collars are not necessarily harmful to your dog’s neck. However, improper fit, size, and placement could contribute to tracheal collapse in dogs. If the equipment rests on the wrong area of the neck or is improperly fitted, the constant applied pressure weakens the cartilage around the windpipe.

Signs of Tracheal Collapse in Dogs

There are various noticeable dog tracheal collapse symptoms. Recognizing your dog’s clinical signs is essential for early diagnosis and effective management of the condition. 

Here are some common indicators that your dog might be experiencing a collapsing trachea:

  • Syncope
  • Cyanosis
  • Honking cough
  • Difficulty breathing
  • Gagging or retching
  • Exercise intolerance

Note that these collapsing tracheal symptoms may vary in severity, and not all of them may be present all the time. If you observe any of these symptoms in your dog, it’s recommended that you consult with your veterinarian for a diagnosis and treatment plan. 

Stages of Tracheal Collapse in Dogs

The degree of collapse in a dog’s trachea varies a lot, and it is often quantified in terms of the percentage of reduction in the airway diameter in the tracheal region. The percentage indicates how severe the collapse is, and it ranges from mild to critical:

  • Mild collapse (grade 1): There’s approximately 25% reduction in the tracheal diameter. Your dog may occasionally cough, especially when excited or pulling on a leash.
  • Moderate collapse (grade 2): The reduction of the tracheal diameter in this stage is around 50%. Symptoms may include more frequent coughing, exercise intolerance, and occasional gagging.
  • Severe collapse (grade 3): The severity increases with up to 75% reduction in the tracheal diameter. Your pet may exhibit persistent coughing, labored breathing, and cyanosis.
  • Critical collapse (grade 4): This is the worst stage of the tracheal collapse condition. Your dog may already have over 75% reduction, leaving less than 10% of the tracheal lumen unobstructed. This is characterized by significant respiratory difficulties, fainting, and constant coughing. 

Note: The symptoms vary depending on where the collapse happens in the dog’s trachea. If it’s in the neck or cervical trachea, the symptoms are usually worse when your dog breathes in, causing a honking cough sound. Meanwhile, if it’s in the chest or thoracic tracheal region, it’s worse when your dog breathes out. 

Treatment of Dog Tracheal Collapse

If your dog is diagnosed with tracheal collapse, your vet may come up with a treatment plan involving a combination of medical management. In some cases, there may be surgical intervention, depending on how severe the condition is. 

The subsequent sections below detail the common approaches to treating dog tracheal collapse:

Medications for Tracheal Collapse

  • Cough suppressants: If your dog coughs, your vet may prescribe cough suppressants to reduce their frequency
  • Anti-inflammatory drugs: Inflammatory medications, like inhaled steroids, help reduce inflammation in the trachea and relieve discomfort.
  • Bronchodilators: A bronchodilator, also known as broncholytic, is a substance inhaled to widen the dog’s airways and improve breathing. 
  • Antibiotics: Antibiotics may also be used to treat any secondary bacterial infections due to tracheal irritation.

Surgical Intervention

  • Trachea stenting: Trachea stenting is a surgical procedure where a tube made of plastic or metal, known as a stent, is inserted into your dog’s trachea to keep it open and from collapsing.  
  • Tracheal ring surgery: Tracheal ring surgery is an operation where the board certified veterinary surgeon places rings around the dog’s trachea to provide structural support to the area and prevent it from collapsing.

Dog Tracheal Collapse Home Treatment

  • Weight management: Your vet may advise you to keep your dog at a healthy weight. This will significantly reduce pressure on the trachea. 
  • Avoiding collars: The collar and leash combination can be harmful to your dog’s neck due to its placement. That said, it’s recommended that you use a size-appropriate, well-designed harness so the pressure is evenly distributed across the shoulders and chest. The Y-shaped harness is the best harness shape you can choose as it avoids the neck area.
  • Managing allergies: Your vet may also advise you to reduce your dog’s exposure to allergens, which may trigger coughing. 
  • Humidifiers: Dry air often causes dryness and irritation signs of the upper respiratory airways and may lead to infections. Hence, your vet may also advise you to use humidifiers at home to add moisture to the air. 

Additional Supportive Care

  • Exercise modification: Part of the management plan may include avoiding strenuous activities for your dog as they can exacerbate tracheal collapse symptoms.
  • Stress reduction: Stressful situations may trigger coughing episodes in humans, and the same can be applied to dogs. You can prevent this by keeping them in a positive mood through using toys or pheromone diffusers. 
  • Supplements: Your vet may prescribe supplements, like omega-3 fatty acids and glucosamine, to help reduce inflammation and support cartilage health, particularly in the dog’s trachea. 

Note that your vet’s treatment plan will depend on the severity of the tracheal collapse condition, the dog’s health, and their response to initial treatments. Hence, it’s vital to work closely with your vet to monitor your canine’s well-being and make necessary adjustments to the treatment. 

Prognosis of Tracheal Collapse

The prognosis for dogs with tracheal collapse depends on how severe the tracheal collapse is and how well it is managed. If it’s between mild and moderate, many dogs can enjoy relatively normal lives so long as they’re given appropriate medical management. On top of that are lifestyle adjustments and regular health monitoring. 

However, if it’s severe, the condition may necessitate a surgical intervention. Early detection of this condition is crucial in alleviating the symptoms and slowing the tracheal collapse’s progression. By doing so, your dog can experience a good quality of life for several years. 

Note: Tracheal collapse is a progressive and incurable disease. However, early interventions and appropriate treatments can improve your dog’s symptoms and slow down the progression of the condition. 

Frequently Asked Questions

What is the Tracheal Collapse Surgery Cost for Dogs?

The tracheal collapse surgery cost for dogs may range from $3,500 to $6,500. However, this may vary depending on the type of surgery required, the clinic’s location, the condition’s complexity, and the clinic or hospital performing the operation. 

Consider consulting with your vet for a more accurate estimate and see if your pet insurance covers a portion of the surgery cost. 

Can Dog Harnesses Cause Tracheal Collapse?

Dog harnesses don’t necessarily cause tracheal collapse so long as they come in the right size and style for your dog. Ensure its straps are placed correctly so the pressure gets distributed across the shoulders and chest while avoiding the delicate area, such as the neck. 

For the most part, dog harnesses, specifically the ones with a Y-shaped design, are considered safe and are unlikely to cause tracheal collapse. These are, in fact, often recommended for dogs prone to the condition. 

What is the Best Dog Tracheal Collapse Home Treatment?

The best dog tracheal collapse home treatment involves maintaining your dog’s healthy weight through proper diet and exercise, using a harness instead of a collar, and avoiding hot and humid environments, which can make breathing more difficult.

You may also opt to use a humidifier to moisten the air and soothe your dog’s airways, and keep your pet from getting exposed to smoke, pollution, and other irritants. As you do these at home, committing to regular vet check-ups and following prescribed medications to manage the symptoms effectively is equally crucial. 

Final Word

Tracheal collapse in dogs is an advancing condition primarily affecting middle-aged, small breeds. However, you must remember that dogs of any size and age can be affected by this disease.
