As a dog owner, it can be worrying to hear your dog coughing. Dogs may cough for a variety of reasons, ranging from mild irritations to serious health conditions. In this article, we'll explore the common causes of coughing in dogs, how to determine if it's something serious, and when to seek veterinary care. We'll also provide some tips on how to help your dog feel better and prevent future coughing episodes.
Common Causes of Coughing in Dogs
-
Kennel Cough One of the most common reasons for coughing in dogs is kennel cough, also known as infectious tracheobronchitis. This highly contagious respiratory infection is caused by a combination of bacteria and viruses, including Bordetella bronchiseptica. Dogs that have been in close contact with other dogs, such as at kennels, dog parks, or grooming facilities, are more likely to catch kennel cough.
Symptoms:
- A dry, hacking cough that sounds like a honking noise
- Gagging or retching after coughing
- Mild fever in some cases
Treatment: Kennel cough often resolves on its own within a couple of weeks. However, if your dog has difficulty breathing or shows signs of lethargy or loss of appetite, consult a vet. In some cases, antibiotics and cough suppressants may be prescribed to help with symptoms.
-
Heart Disease Dogs with heart disease may also develop a chronic cough. This happens when the heart becomes enlarged or fails to pump blood effectively, leading to fluid buildup in the lungs. The condition is often seen in older dogs or breeds predisposed to heart problems, such as Cavalier King Charles Spaniels or Boxers.
Symptoms:
- Persistent coughing, especially at night or after exercise
- Difficulty breathing
- Lethargy or fainting
- Bluish gums (a sign of poor oxygenation)
Treatment: If heart disease is suspected, a vet will perform diagnostic tests, such as X-rays, ultrasounds, or blood tests. Medications to manage heart failure, reduce fluid buildup, and improve heart function may be prescribed.
-
Tracheal Collapse Smaller dog breeds, such as Chihuahuas, Yorkshire Terriers, and Pomeranians, are prone to tracheal collapse, a condition where the cartilage in the windpipe weakens and collapses, obstructing airflow.
Symptoms:
- A dry, honking cough, often triggered by excitement or pressure on the neck
- Difficulty breathing or wheezing
- Gagging or retching
Treatment: Tracheal collapse is often managed with medications that reduce inflammation and coughing. In severe cases, surgery may be necessary to stabilize the trachea.
-
Allergies Just like humans, dogs can suffer from allergies that cause coughing. Common allergens include pollen, dust, mold, and cigarette smoke. Allergies can irritate the respiratory system, leading to coughing.
Symptoms:
- Occasional coughing, especially during certain times of the year
- Itchy skin, sneezing, or watery eyes
- Reverse sneezing (a rapid, forceful inhalation through the nose)
Treatment: If allergies are suspected, your vet may recommend antihistamines or corticosteroids to reduce symptoms. Limiting your dog’s exposure to known allergens can also help.
-
Respiratory Infections Coughing can be a symptom of various respiratory infections, such as pneumonia, bronchitis, or canine influenza. These infections can be bacterial, viral, or fungal and often affect dogs with weakened immune systems or young puppies.
Symptoms:
- Wet, productive cough (coughing up mucus or phlegm)
- Fever
- Difficulty breathing
- Lethargy
Treatment: Depending on the cause of the infection, your vet may prescribe antibiotics, antivirals, or antifungal medications. Rest and plenty of fluids are important for recovery.
-
Foreign Objects Dogs can accidentally inhale or swallow foreign objects, such as grass, dirt, small toys, or food, which can become lodged in their throat or airway and trigger coughing as the body tries to expel the object.
Symptoms:
- Sudden coughing or choking
- Pawing at the mouth or face
- Difficulty breathing or swallowing
Treatment: If you suspect that your dog has something stuck in its throat, immediate veterinary attention is required. Never attempt to remove an object yourself unless it’s clearly visible and easy to access.
-
Parasites Certain types of parasites, such as heartworms or lungworms, can cause coughing in dogs. Heartworm disease, in particular, is serious and can lead to heart failure if left untreated. Lungworms, though less common, can also cause respiratory problems.
Symptoms:
- Persistent cough
- Exercise intolerance
- Weight loss
- Difficulty breathing
Treatment: Heartworm and lungworm infections require veterinary treatment. Preventative medications are available for heartworms, and early diagnosis and treatment can significantly improve your dog’s outcome.
-
Environmental Irritants Exposure to environmental irritants, such as smoke, pollution, or household cleaning products, can cause a temporary cough in dogs. If the irritants persist, chronic coughing or lung damage can occur.
Symptoms:
- Coughing after exposure to specific irritants
- Watery eyes or nasal discharge
- Reverse sneezing
Treatment: Reducing your dog’s exposure to irritants, improving ventilation in the home, and using pet-safe cleaning products can help alleviate symptoms.
When Should You Be Concerned?
Coughing isn’t always a reason for concern, but certain signs indicate that you should seek veterinary care immediately:
- Coughing that lasts for more than a week: Persistent coughing can be a sign of an underlying health issue that needs treatment.
- Difficulty breathing: If your dog is struggling to breathe, with open-mouth breathing, panting, or gasping, this is a medical emergency.
- Coughing up blood: This could indicate trauma or a serious infection.
- Lethargy, loss of appetite, or weight loss: These are warning signs that your dog is unwell and needs to see a vet.
- Blue gums or tongue: This is a sign that your dog isn’t getting enough oxygen.
How to Help Your Dog at Home
If your dog is experiencing mild coughing and your vet has ruled out any serious conditions, there are ways you can help soothe their throat and make them more comfortable:
- Humidifier: Using a humidifier in your dog’s resting area can help soothe irritated airways.
- Keep them calm: Excitement and exertion can make coughing worse, so it’s important to keep your dog calm and quiet.
- Hydration: Ensure that your dog is drinking plenty of water to help thin mucus and keep the throat hydrated.
- Limit exposure to irritants: Keep your dog away from smoke, chemicals, or dust that could irritate their respiratory system.
Preventing Coughing in Dogs
Preventing coughing in dogs starts with proper health care and minimizing exposure to infectious diseases and environmental irritants. Here are some preventive tips:
- Vaccinations: Keep your dog’s vaccinations up to date, particularly for kennel cough, canine influenza, and other respiratory illnesses.
- Regular vet check-ups: Routine visits to the vet will help catch any underlying health conditions early.
- Heartworm prevention: Use monthly heartworm prevention medications to protect your dog from this deadly parasite.
- Clean living environment: Keep your home well-ventilated and free from dust, smoke, and harsh chemicals that can irritate your dog’s lungs.
- Healthy weight and exercise: Maintaining a healthy weight and regular exercise can help improve your dog’s heart and lung health.
Final Thoughts
Coughing in dogs can be caused by a variety of factors, ranging from mild irritations to more serious health issues. While occasional coughing may not be a cause for concern, persistent or severe coughing should be addressed by a veterinarian. Understanding the common causes and knowing when to seek help can ensure that your dog stays healthy and happy.
By keeping an eye on your dog’s overall health and taking preventive measures, you can help minimize the chances of them developing conditions that cause coughing. Remember, if you’re ever in doubt, consult your vet for guidance tailored to your dog’s specific needs.
