As a pet owner, it can be concerning when your beloved furry friend starts coughing. Just like humans, dogs can develop coughs for a variety of reasons. It could be a simple irritation or something more serious.

In order to identify the cause of your dog’s cough, it’s important to become a detective and explore all the possible factors. In this article, we will uncover the common causes of coughing in dogs and offer guidance on when to seek veterinary care.

1. Respiratory Infections

Respiratory infections, such as kennel cough, are a common cause of coughing in dogs. Kennel cough is highly contagious and is typically contracted in places where dogs gather, such as boarding kennels, dog parks, or veterinary clinics.

The cough associated with kennel cough is often dry and honking, similar to the sound of a goose. Other symptoms may include sneezing, nasal discharge, and fever.

2. Heart Disease

Coughing can also be indicative of heart disease in dogs. When the heart is not able to pump blood effectively, fluid can accumulate in the lungs, resulting in coughing.

This type of cough is often accompanied by lethargy, difficulty breathing, and a bluish tinge to the gums. If you suspect heart disease as the cause of your dog’s cough, it is crucial to seek immediate veterinary attention.

3. Allergies

Allergies are prevalent among dogs, just like in humans. Dogs can develop allergies to various substances, including pollen, dust mites, mold, or certain foods.

Coughing due to allergies is typically associated with other symptoms like itching, sneezing, watery eyes, and skin rashes. Identifying and avoiding the allergen can help alleviate the coughing in allergic dogs.

4. Collapsed Trachea

A collapsed trachea is a condition commonly found in small dog breeds, such as Chihuahuas and Yorkshire Terriers. It occurs when the rings of cartilage that support the trachea weaken, causing the airway to collapse during breathing.

Coughing is a common symptom, particularly during excitement or exercise. Mild cases can be managed with lifestyle changes and medication, while severe cases may require surgical intervention.

5. Foreign Body

Occasionally, dogs may cough due to the presence of a foreign object lodged in their airway. This could be anything from a small toy to a piece of bone or even a plant material. The coughing is often sudden and intense, accompanied by choking or gagging.

If you suspect a foreign body is causing your dog’s cough, it is essential to consult a veterinarian immediately to prevent more serious complications.

6. Canine Influenza

Similar to humans, dogs can also contract the flu. Canine influenza is a highly contagious respiratory virus that can cause coughing, sneezing, nasal discharge, and fever. It spreads quickly among dogs in close contact, such as in kennels or dog shows.

Vaccination is available for protection against canine influenza, and if your dog shows flu-like symptoms, it is important to isolate them from other dogs and seek veterinary care.

7. Heartworm Disease

Heartworm disease is a serious and potentially fatal condition caused by parasitic worms that live in the heart and blood vessels of infected dogs.

Coughing is one of the symptoms, along with difficulty breathing, reduced exercise tolerance, and weight loss. It is vital to prevent heartworm disease through regular veterinary check-ups and the use of preventive medications.

8. Pneumonia

If left untreated, respiratory infections or aspiration of foreign material can progress into pneumonia. Pneumonia is an inflammation or infection of the lungs, which can lead to severe coughing in dogs.

Other symptoms may include fever, difficulty breathing, lethargy, and loss of appetite. Veterinary care is crucial to diagnose and treat pneumonia, as it can be life-threatening if not addressed promptly.

9. Cigarette Smoke

Exposure to secondhand cigarette smoke can cause chronic coughing in dogs. The irritation from smoke can lead to respiratory problems and coughing fits. If you are a smoker, it’s vital to keep your dog away from the harmful effects of smoke.

Similarly, avoiding areas where others smoke will also help reduce the chances of your dog developing a persistent cough.

10. Pulmonary Edema

Pulmonary edema refers to fluid accumulation in the lungs, often due to heart problems, kidney disease, or poisoning.

The cough associated with pulmonary edema is typically accompanied by difficulty breathing, rapid breathing, and a bluish tinge to the gums. Immediate veterinary care is necessary to address the underlying cause and provide appropriate treatment.

While this list covers many of the common causes of coughing in dogs, it’s important to remember that every dog is unique, and the cause of their cough may not fit into these categories.

If your dog is coughing persistently, experiencing difficulty breathing, or showing other concerning symptoms, it is crucial to consult with a veterinarian. Early detection and proper treatment can help your furry friend recover quickly and avoid further complications.
