Why is my Bernese Mountain Dog coughing

Heart disease

Heart disease causes rapid breathing and coughing, among other symptoms. It is common in older Bernese Mountain Dogs. 

If your Bernese Mountain Dog has been diagnosed with heart disease, they may cough when resting, lying down, or sleeping, when the condition worsens.

Tracheal collapse

Tracheal collapse occurs when a Bernese Mountain Dog’s windpipe collapses and flattens which leaves a small passage for air to flow into the lungs.

The collapse occurs dues to tracheal cartilage collapse. The restricted airflow through the trachea causes a Bernese Mountain Dog to have respiratory distress, cough, and also gag when eating or drinking.

Tracheal collapse is common in middle-aged or older small breed dogs but can also occur in large breed dogs such as the Bernese Mountain Dog.

Environmental allergies

Allergic bronchitis is caused by the inhalation of irritants such as dust, pollen, aerosol spays, mildew, dust mites, grain mites, or cigarette smoke.

It is a persistent inflammation of the lower respiratory tract which leads to airway swelling and constriction of airflow into the lungs. 

The inflammation also causes the production of mucus in the bronchial tubes which further narrow the airway. 

Bernese Mountain Dogs with bronchitis have a dry hacking cough that worsens during exercise or when overexcited.

Scarring of the airways can also occur and further weaken the bronchi membrane, which leads to wheezing and coughing.

Ingestion of foreign objects

Bernese Mountain Dogs can ingest foreign objects which leads to obstruction of the throat, which causes gagging and coughing. 

Foreign objects that can be ingested include sticks, broken toys, small balls, or bones, which block a dog’s throat.

Other conditions that are less common but cause Bernese Mountain Dog coughing include laryngeal (windpipe) paralysis, canine influenza, distemper, heartworm disease, and lung cancer.


Bernese Mountain Dog coughing can be an indication of a serious underlying problem that might worsen and become fatal if left untreated.

Heart disease, infections, tracheal collapse, cancer, and obstruction of the throat are all serious conditions that deteriorate a Bernese Mountain Dog’s health. They are also life-threatening.

Early diagnosis and treatment of these ailments prevent the fatal outcomes, therefore it is important to have your dog examined to determine the cause of the coughing.

When to seek help for Bernese Mountain Dog coughing

Occasional Bernese Mountain Dog coughing is common and normal especially after eating or drinking too quickly, or as a response to an irritation in the throat. Recurrent coughs are however a cause of concern and require medical attention.

First, check if the coughing is due to an ingested foreign object that obstructs the throat. If there is an object, immediately seek medical attention.

Contact your veterinarian when your Bernese Mountain Dog’s cough lasts for more than a week and also when other symptoms of illness are present, or if your dog also has a preexisting health condition.

When coughing prolongs and also shows up with other symptoms of illness such as wheezing, drooling, weakness, dry heaving, or difficulty in breathing it means there is an underlying problem.

You can also take a video recording of your Bernese Mountain Dog when coughing to provide it to your veterinarian to show what your dog was experiencing.

During your dog’s checkup, the veterinarian will conduct a physical exam and also ask you questions about your dog’s symptoms to help in the diagnosis.  

The questions asked include:  

  • The sound of the cough, that is, whether the cough was a dry hacking cough or a productive/ wet cough
  • The progression of the cough ( if the cough was worsening)
  • The duration of the cough (how long the cough has been experienced)

Diagnostic tests will also be conducted to reach a diagnosis.

The treatment of Bernese Mountain Dog coughs varies depending on the underlying cause. Treatment may include:

  • Medication for disease or infections
  • Removal of esophageal obstructions
  • Surgery in some cases for the treatment of tracheal collapse


Bernese Mountain Dog coughing can be very alarming. Most often it does not need medical attention when it is caused by eating or drinking too quickly but it can also be due to an underlying health condition.

Coughing can be caused by different factors but it is important to have your Bernese Mountain Dog examined to check for the cause. 

Early detection of ailments can save a Bernese Mountain Dog’s life by preventing their condition from worsening. Immediately seek medical attention when your Bernese Mountain Dog has coughs that last for a long time or they present other symptoms of illness.
