Common Causes of Coughing in Dogs

Coughing in dogs is a common symptom that can be caused by a variety of factors. It is important for dog owners to understand the potential causes of coughing in order to provide their pets with the appropriate care and treatment. Here are some common causes of coughing in dogs:

Respiratory infections

Respiratory infections, such as pneumonia or bronchitis, can lead to coughing in dogs. These infections can be caused by bacteria, viruses, or fungi, and can result in inflammation of the respiratory tract. Dogs with respiratory infections may have a persistent cough, and difficulty breathing, and may exhibit other symptoms such as fever or nasal discharge.

Allergies

Just like humans, dogs can also suffer from allergies. Allergens such as pollen, dust mites, or certain foods can trigger an allergic reaction in dogs, leading to coughing. Allergic coughs are often accompanied by other symptoms like sneezing, itching, or watery eyes. Identifying and avoiding the allergen can help alleviate the coughing symptoms in allergic dogs.

Kennel cough

Kennel cough, also known as infectious canine tracheobronchitis, is a highly contagious respiratory infection that can cause a persistent cough in dogs. It is commonly spread in places where dogs are in close contact with each other, such as kennels, dog parks, or grooming salons. Kennel cough is usually caused by a combination of viruses and bacteria, and can be prevented through vaccination.

Heart disease

Heart disease can also be a cause of coughing in dogs. When the heart is not functioning properly, it can lead to fluid accumulation in the lungs, causing coughing. Dogs with heart disease may also exhibit other symptoms such as difficulty breathing, loss of appetite, and lethargy. Treating the underlying heart condition is essential in managing the coughing symptoms.

Collapsing trachea

In dogs with a collapsing trachea, the cartilage rings that support the trachea weaken, causing the trachea to flatten and narrow. This can lead to coughing, especially during exercise or excitement. Small dog breeds, such as Pomeranians or Chihuahuas, are more prone to this condition. Managing the coughing symptoms of a collapsing trachea may involve medication or, in severe cases, surgery.

Symptoms of Coughing in Dogs

Recognizing the symptoms associated with coughing in dogs is crucial in determining the underlying cause and seeking appropriate veterinary care. Here are some common symptoms that may accompany coughing in dogs:

Persistent cough

A persistent or chronic cough is one of the most common symptoms of respiratory issues in dogs. It may vary in intensity, frequency, and sound, depending on the cause of the cough. If your dog has been coughing for more than a few days, it is important to seek veterinary care for a proper diagnosis.

Wheezing sounds

Wheezing sounds, often described as a high-pitched whistling noise, can accompany coughing in dogs. Wheezing indicates obstruction in the airways, which can be caused by inflammation, mucus build-up, or narrowing of the air passages.

Difficulty breathing

Coughing can sometimes be associated with difficulty breathing or shortness of breath in dogs. This can be due to various factors, such as respiratory infections, heart problems, or obstructed airways.

Loss of appetite

Coughing and respiratory issues can often lead to a loss of appetite in dogs. If your dog is coughing and showing a decreased interest in food, it may be an indication of an underlying medical condition that requires attention.

Lethargy

Dogs experiencing coughing episodes may exhibit lethargy or a lack of energy. This can be a result of reduced oxygen flow, discomfort associated with coughing, or the overall impact of an underlying illness.

Why Do Dogs Cough?

When to Seek Veterinary Care

While occasional coughing in dogs may not always be a cause for concern, there are certain circumstances when it is important to seek veterinary care for your furry friend. Here are some situations that warrant a visit to the veterinarian:

Coughing lasts for more than a few days

If your dog’s coughing persists for more than a few days or if it becomes more frequent or severe, it is essential to consult a veterinarian. Prolonged or worsening coughing can indicate an underlying condition that requires medical intervention.

Cough is accompanied by other severe symptoms

If your dog’s cough is accompanied by other severe symptoms such as difficulty breathing, high fever, excessive lethargy, coughing up blood, or a bluish tinge to the gums or tongue, it is crucial to seek immediate veterinary care. These symptoms could indicate a serious and potentially life-threatening condition.

Coughing becomes progressively worse

If your dog’s coughing episodes become progressively worse, despite initial treatment or management, it is important to have your pet reassessed by a veterinarian. Worsening coughing may indicate a need for a different treatment approach or further investigation into the underlying cause.

Concern for underlying medical condition

If you have any concerns or suspicions about the underlying cause of your dog’s coughing, it is always best to consult a veterinarian. They can perform a thorough examination, conduct necessary tests, and provide appropriate treatment options based on their findings.

Diagnosing the Cause of Canine Cough

Determining the exact cause of coughing in dogs can be challenging as it can be attributed to various factors. Luckily, there are several diagnostic techniques that veterinarians utilize to identify the underlying cause. These may include:

Physical examination

A thorough physical examination of your dog allows the veterinarian to assess their overall health and check for any abnormalities. They may listen to the lungs and heart for any abnormal sounds, examine the throat and mouth, and feel for enlarged lymph nodes or other organs.

X-rays or other imaging tests

X-rays or other imaging tests, such as ultrasound or CT scans, may be recommended to evaluate the lungs, heart, or airways. These tests can help identify any abnormalities or changes that may be causing the coughing symptoms.

Blood tests

Blood tests can provide valuable information about your dog’s overall health and detect any underlying infections or imbalances. They can also help determine if there are any underlying heart conditions that may be contributing to the coughing.

Sampling mucus or fluid

Collecting samples of mucus or fluid from the respiratory tract can be useful in identifying the specific cause of the cough. This may involve a tracheal wash or bronchoscopy, where a thin tube is inserted into the airways to collect samples for laboratory analysis.

Bronchoscopy or tracheal wash

Bronchoscopy or tracheal wash procedures allow for direct visualization of the airways and collection of samples. These procedures may be recommended if the underlying cause of coughing cannot be determined through other diagnostic methods.

Treatment Options for Coughing Dogs

The treatment of coughing in dogs depends on the underlying cause identified through diagnostic procedures. Here are some common treatment options:

Medication to treat underlying cause

If the coughing is due to a specific condition, such as a respiratory infection or heart disease, medication may be prescribed to target the underlying cause. Antibiotics, antiviral drugs, or heart medications may be prescribed to address the specific condition affecting your dog.

Cough suppressants

In certain cases, cough suppressants may be prescribed to provide temporary relief from the cough and allow your dog to rest and heal. However, it is important to note that cough suppressants should only be used under the guidance of a veterinarian, as they can mask the symptoms of an underlying condition.

Antibiotics for infections

If the coughing is caused by a bacterial infection, antibiotics may be prescribed to help clear the infection. It is important to complete the full course of antibiotics, even if symptoms improve, to prevent the development of antibiotic-resistant bacteria.

Heart medications

If heart disease is the underlying cause of the cough, medications may be prescribed to manage the condition. These medications can help improve heart function, reduce fluid build-up in the lungs, and alleviate coughing symptoms.

Surgery for certain conditions

In some cases, surgical intervention may be necessary to treat the underlying cause of coughing. This may involve procedures to repair a collapsing trachea or remove obstructions from the airways. Surgical options will depend on the specific condition affecting your dog and should be discussed with a veterinarian.
