Chronic Cough in Dogs
Chronic cough in dogs is a persistent or recurring cough that lasts for more than two months. This cough is not only annoying for the dog, but can also be an indicator of serious health problems.
Can Occur with the Following Diseases:
Basics and possible causes
Chronic cough in dogs can be caused by a variety of reasons, ranging from simple irritations to serious diseases. One of the most common causes is chronic bronchitis, in which the dog’s airways are permanently inflamed. This inflammation can be triggered by allergens, irritants or infections.
Another common cause of chronic cough is heart disease, especially mitral valve insufficiency, which is more common in older dogs. In this disease, a faulty closure of the mitral valve leads to inadequate blood flow and can accumulate fluid in the lungs, which leads to cough.
Infectious causes such as kennel cough, a highly contagious respiratory disease, can also lead to long-lasting cough. This disease is often caused by bacteria and viruses and occurs especially in environments with high dog density.
Parasites such as lungworms can also cause chronic cough. These parasites infect the respiratory tract and lead to irritation and inflammatory conditions. Likewise, tumors or foreign bodies in the respiratory tract can be the cause of a persistent cough.
In addition, environmental factors such as smoking near the dog or staying in heavily polluted areas can irritate the dog’s airways and cause chronic cough.
Typical accompanying symptoms
-
Vomiting or Gagging: Often a gagging sound accompanies the cough, as if the dog wants to cough something up, which can lead to vomiting.
-
Difficulty breathing: A dog with chronic cough may also show shortness of breath or rapid breathing, especially after exertion.
-
Lethargy: Due to the strain of constant cough, the dog may appear lethargic or less active than usual.
-
Loss of appetite: The persistent cough can lead to the dog showing less interest in food.
-
Weight loss: If the symptoms persist for a longer period of time, it can lead to unwanted weight loss, as the dog eats less or does not sufficiently utilize nutrients.
-
Sneezing and nasal discharge: In some cases, the cough may be accompanied by sneezing or a clear to yellowish nasal discharge.
-
Bluish tongue or gums: In the case of serious breathing problems, a lack of oxygen can lead to a bluish discoloration of the mucous membranes.
When to visit the vet?
A veterinarian should be consulted if the cough lasts longer than a week or if it worsens. In particular, if the cough is accompanied by shortness of breath, bloody sputum or a very poor general condition, an immediate visit to the veterinarian is necessary.
Another warning sign is when the dog cannot find a breathing rhythm despite resting or when the cough is so severe that it significantly impairs the dog's daily life. In these cases, an immediate veterinary examination is essential.
Even in dogs known to suffer from heart or lung problems, the veterinarian should be consulted immediately if a new or worsened cough occurs.
Symptom recognition for animal owners and veterinary diagnostic procedures
For the pet owner, it is important to observe the coughing characteristics of the dog. Note when the cough occurs, what it sounds like (e.g. dry or moist) and whether it is triggered by certain activities. This information is useful for the veterinarian to make an accurate diagnosis.
The veterinarian will first perform a thorough clinical examination to assess the general condition of the dog. This may include listening to the lungs and heart to identify noises that may indicate a disease.
For further clarification, X-rays of the chest could be taken to assess the structure of the lungs and heart. Blood tests can also be performed to detect inflammatory conditions, infections or other systemic problems.
In some cases, a bronchoscopy may be necessary, in which a camera is inserted into the airways to obtain a direct view of possible inflammatory conditions or foreign bodies. The examination of lung fluid or tissue can also contribute to the diagnosis.
What can pet owners do and professional therapy options
As a pet owner, you can take some measures to alleviate the dog’s symptoms and improve its quality of life. Make sure that your dog lives in a smoke-free environment and avoid irritants such as perfume or household cleaners that could worsen the cough.
Avoid excessive physical exertion that could increase the cough. Instead, gentle walks and quiet activities are recommended. Make sure your dog drinks enough to keep the mucous membranes moist and relieve the cough.
A humidifier can help in the apartment to increase the humidity and thus soothe the dog’s airways. A balanced diet that is tailored to the specific needs of your dog can also contribute to stabilizing his health.
If prescribed by the veterinarian, medications such as cough suppressants or anti-inflammatory drugs should be administered regularly and as directed. When using medication, it is important to follow the dosage recommendations exactly and to observe the dog for possible side effects.
In any case, close cooperation with the veterinarian is crucial to treat the cause of the cough and ensure the best possible care for your dog.
Outlook on current research
Research into chronic cough in dogs focuses on identifying biomarkers that could facilitate early diagnosis. These biomarkers could be specific proteins or genetic patterns that are detectable in the blood or in the breath. Such non-invasive testing methods could reduce the need for invasive diagnostic procedures in the future and enable faster, more accurate diagnosis.
Another area of research examines the role of environmental factors and lifestyle on the development of chronic cough. Studies show that air pollution, second-hand smoke, and even certain household cleaners can increase the risk of respiratory diseases in dogs. Researchers are working to identify specific compounds that are responsible for the cough in order to develop targeted prevention strategies.
With regard to treatment options, intensive research is being carried out into new drugs that combine anti-inflammatory and expectorant properties. These drugs could alleviate the symptoms more effectively without causing the side effects that are often associated with conventional therapies. In addition, alternative therapy approaches are being investigated, such as laser therapy and acupuncture, which show promising results in alleviating chronic cough.
Another exciting field of research is the role of the microbiome in respiratory health. Scientists are investigating how the balance of microorganisms in the respiratory tract affects the immune response and may contribute to the development or worsening of cough. This research could lead to probiotic treatments that restore the microbiome to balance and thus relieve the cough.
Genetics also plays a crucial role in research on chronic cough in dogs. Scientists are trying to identify genetic predispositions that make certain breeds more susceptible to respiratory diseases. By understanding these genetic factors, breeders could breed more specifically in the future to reduce the risk of chronic cough.
In summary, research on chronic cough in dogs is very dynamic and benefits from new technologies and interdisciplinary approaches. While there are still many open questions, the results of these studies could lead to better diagnostic and treatment options in the near future and significantly improve the quality of life of dogs.
