If you’ve ever heard your pup blurt out a strange honking cough, or maybe even struggle to breathe, then you know something’s wrong. One of the reasons could be tracheal collapse.
In simple terms, it’s a condition that occurs when the trachea, or windpipe, weakens and starts to flatten. This makes it harder for air to move in and out of the lungs. As a result, dogs will experience respiratory symptoms. The condition is also progressive and worsens over time.
In this blog, we’ll talk more about tracheal collapse in dogs, from the causes to the treatment options.
What Causes Tracheal Collapse in Dogs?
Tracheal collapse is primarily caused by a weakening of the cartilage rings that support the windpipe.
Think of it as a flexible tube made up of small, C-shaped cartilage rings. In healthy dogs, these rings hold the airways open. In dogs with tracheal collapse, these rings begin to soften and lose shape.
Genetic Causes
Some dog breeds are just born with weaker tracheal cartilage, meaning they are more prone to collapse as they grow older. These dogs may start showing signs of respiratory issues earlier in life. This is especially common in dogs such as:
Age
As dogs age, their tracheal cartilage can naturally weaken and lose their rigidity. This degeneration reduces the trachea’s ability to stay open during breathing. This progressively increases the risk of collapse and other symptoms.
Chronic Respiratory Disease
Conditions such as chronic bronchitis and kennel cough can cause frequent inflammation and coughing. Over time, this constant irritation can damage the tracheal lining and the cartilage rings. The more this goes on, the more strain is placed on the vulnerable airway.
Obesity
Excess weight can also put additional strain and pressure on a dog’s chest and airway. This makes it more difficult to breathe. Additionally, obese dogs tend to have reduced respiratory efficiency, worsening the effects of tracheal collapse.
Environmental Irritants
Constant exposure to smoke, dust, pollen, and other irritants can also inflame a dog’s airways. Over time, dogs with sensitive tracheas can experience coughing fits, further weakening the structure. Dogs with other pre-existing conditions related to this area will be affected greatly.
Collar Pressure
Excessive use of collars when paired with a leash can put direct pressure on the trachea. Repeated pressure and sudden jerks can damage the cartilage, leading to collapse. A harness is always the better and safer choice for dogs.
How to Tell if Your Dog Has a Collapsed Trachea?
The signs often consist of respiratory issues that can worsen over time. Common symptoms of tracheal collapse in dogs include:
Honking cough. A honking cough is often the most recognizable symptom of canine tracheal collapse. The situation worsens when dogs become excited, exercise, are pulled on a leash, or are exposed to prolonged heat.
Wheezing or labored breathing. You might also hear a raspy and noisy sound when your dog breathes. This happens due to the narrowing of the airways, which restricts airflow. Dogs will have more difficulty catching their breath and may take time to recuperate.
Exercise intolerance. Dogs with tracheal collapse often tire quickly or struggle to keep up on walks and playtime. They may choose to stop more frequently and will have significantly lower energy levels. In some cases, they’ll decide not to move at all.
Gagging or retching. Some dogs gag or retch to clear their throat, which is often a response to tracheal irritation.
Blue or pale gums. When a dog isn’t getting enough oxygen, the gums may appear pale or blue. If you notice this, then it’s considered a medical emergency.
Fainting or collapse. In extreme cases of oxygen deprivation, dogs may faint and collapse. This should never be ignored.
