A dog can cough just like a human and just like humans there can be multiple reasons why your dog is coughing.\u00a0<\/span><\/p>\n

Here are 12 reasons why your dog might be coughing right now – pulling on their lead, kennel cough, pneumonia, canine influenza, canine parainfluenza, heart disease, heartworm, allergies, foreign objects stuck in throat, tracheal collapse, laryngeal paralysis and <\/span>brachycephalic airway obstruction syndrome<\/span><\/a> (BOAS).\u00a0<\/span><\/p>\n

The cause can depend upon loopholes in your dog\u2019s preventive healthcare, age, breed and weight. Obese flat-faced dogs are more prone to airway obstructions (BOAS) and senior large-breed dogs are more at risk of laryngeal paralysis.\u00a0<\/span><\/p>\n

What should you do when your dog is coughing?<\/span><\/h2>\n

You need to keep a close eye on your dog\u2019s coughing frequency and triggers.\u00a0<\/span><\/p>\n

Taking a video of your dog while they cough can also help the veterinarian reach a conclusion.\u00a0<\/span><\/p>\n

Make notes of the fluids coming out of your dog\u2019s mouth during a coughing episode. The fluids can be plain water, foam, mucous and\/or blood.\u00a0<\/span><\/p>\n

You should NEVER use human cough syrups and anti-allergics for your dog\u2019s coughing without consulting a veterinarian. <\/span>Human cough and cold medicines<\/span><\/a> can be very harmful for dogs. So always seek the advice of a veterinarian even if you are sure it is nothing but a mild cold.\u00a0<\/span><\/p>\n

Why is your dog coughing: Let\u2019s find out the reasons<\/span><\/h2>\n

12 Reasons Your Dog Might Be Coughing<\/span><\/h3>\n

\"This<\/p>\n

1. Incorrect collar and pulling on the leash<\/span><\/h2>\n

It is one of the most common reasons for a dog\u2019s intermediate coughing. The incorrect collar type and size combined with a highly energetic dog who pulls on their lead can cause your dog to cough frequently when on a walk.\u00a0<\/span><\/p>\n

Be careful because incorrect collars can cause permanent damage to your dog\u2019s throat and neck. A martingale collar or harness is often a better alternative to conventional dog collars. (Tilley & Smith, 2015)<\/span><\/p>\n

2. Kennel cough<\/span><\/h2>\n

In India, kennel cough is very common among streeties and shelter dogs. Even an unvaccinated house pupper can catch kennel cough (<\/span>Bordetella sp.<\/span><\/i>) after spending a couple of days at a boarding kennel.\u00a0<\/span><\/p>\n

Coughing due to kennel cough has a typical \u201chonking\u201d sound. It is treatable but dogs do suffer pain and discomfort during the infection period. The only way to protect your dog from kennel cough is by giving them timely vaccinations. (American Veterinary Medical Association [AVMA], 2023)<\/span><\/p>\n

3. Canine influenza (Dog Flu)<\/span><\/h2>\n

Dog flu or canine influenza<\/span><\/a> is a highly contagious respiratory disease that causes respiratory tract infection in dogs. While it is prevalent among shelter and streetside dogs, direct contact can make pet dogs vulnerable to canine flu as well.\u00a0<\/span><\/p>\n

Sadly, canine influenza (dog flu) vaccines aren\u2019t yet available in India. So, the veterinarians typically treat the dogs with dog flu according to their symptoms. Canine influenza can take between 7 days and 30 days to resolve. (Padrid, 2000)<\/span><\/p>\n

4. Canine parainfluenza<\/span><\/h2>\n

Canine parainfluenza has symptoms similar to influenza. It can be a reason why your dog is coughing, especially if they are unvaccinated. It is a viral lung infection and has no specific treatment. Vets have to offer symptomatic treatment to the affected dog.\u00a0<\/span><\/p>\n

However, parainfluenza in dogs can make a dog or pup more susceptible to bacterial infections, such as Kennel Cough. Always <\/span>vaccinate your puppy or dog<\/span><\/a> against the common contagious diseases including parainfluenza and Kennel Cough. (WSAVA, 2022)<\/span><\/p>\n

5. Heart disease(s)<\/span><\/h2>\n

Coughing in dogs is one of the most common signs of heart diseases in dogs. If your dog has a persistent cough with difficulty in breathing it can be a sign of congestive heart failure.\u00a0<\/span><\/p>\n

However, with modern diagnostics and medication, it is possible to improve the quality of a dog\u2019s life. In case your dog is coughing a lot, you need to see a veterinarian as soon as possible. (American College of Veterinary Internal Medicine [ACVIM], 2019)<\/span><\/p>\n

6. Pneumonia (lung congestion)<\/span><\/h2>\n

Pneumonia in dogs is not a disease in itself. It can be a result of infection(s) of the lower respiratory tract. In the <\/span>cases of pneumonia in dogs<\/span><\/a> the lungs and airways are inflamed. It causes difficulties in breathing leading to chronic cough.\u00a0<\/span><\/p>\n

Pneumonia in dogs is treatable and curable if the cause is identified on time. So, it\u2019s very important to consult a veterinarian if you notice your dog coughing. (Padrid, 2000)<\/span><\/p>\n

7. Allergies (perfumes and room fresheners)\u00a0<\/span><\/h2>\n

Just like us dogs can cough due to allergies. Environmental allergens including dust mites, pollens and strong air fresheners can make your dog cough.\u00a0<\/span><\/p>\n

Allergic cough is typically accompanied by a runny nose, sneezing and watery eyes. However, these are also common signs of the beginning of a viral infection. You need to consult a vet even if your dog has a history of allergic cough. (Tilley & Smith, 2015)<\/span><\/p>\n

8. Foreign objects stuck in throat<\/span><\/h2>\n

Dogs explore the world through their noses. They often inhale small amounts of dust, grass particles, pollen and inorganic particles. When these irritate their throat, they try to hack and cough.\u00a0<\/span><\/p>\n

In some cases, your dog can cough the irritants out. However, if the cough persists for longer than 24 hours, you should take your dog to a pet clinic that has complete in-house diagnostics. Your dog might need the help of a veterinarian for the removal of the foreign object. (Padrid, 2000)<\/span><\/p>\n

9. Heartworm<\/span><\/h2>\n

Heartworms are more common than you think in a tropical country like India. Infected <\/span>mosquitoes transfer heartworm larvae<\/span><\/a> to a dog\u2019s bloodstream and these worms enter the dog\u2019s heart.\u00a0<\/span><\/p>\n

When a dog coughs due to the presence of heartworms they have a loud, honking cough which is somewhat similar to the cough due to Kennel Cough. If your dog is coughing immediately after mild to moderate exercise, there\u2019s a chance your dog has heartworms.\u00a0<\/span><\/p>\n

Heartworms in dogs are treatable depending on the level of infestation. Thankfully, heartworm infection is preventable. (American Heartworm Society, 2022)<\/span><\/p>\n

10. Tracheal collapse<\/span><\/h2>\n

Tracheal collapse (collapse of the windpipe) is an emergency in dogs. Coughing due to tracheal collapse is persistent, dry and harsh. Coughing almost always leads to wheezing due to difficulty in breathing. The dog\u2019s gums and tongue may turn blue due to the lack of enough oxygen.\u00a0<\/span><\/p>\n

Although it is an emergency, correct and timely <\/span>treatment for tracheal collapse<\/span><\/a> can save a dog\u2019s life. Hence, never take loud \u201chonking\u201d cough combined with breathing difficulties lightly in any dog irrespective of breed, age and size. Always take them to an emergency veterinary clinic. (Dodd & Moon, 2021)<\/span><\/p>\n

11. Laryngeal paralysis<\/span><\/h2>\n

Larger breeds, such as the Labrador Retriever are more prone to <\/span>laryngeal paralysis<\/span><\/a> as compared to others. The most common initial signs include coughing after exercise, wheezing, excessive panting and a change in the barking sound.\u00a0<\/span><\/p>\n

Thankfully, it is more common in senior dogs and the dogs with laryngeal paralysis live their expected lifespan without any compromise in their quality of life. However, it\u2019s only possible with proper diagnosis and professional medical help. (Rishniw & Ljungvall, 2016)<\/span><\/p>\n

12. BOAS<\/span><\/h2>\n

BOAS (Brachycephalic Obstructive Airway Syndrome) is a lifelong disorder that affects most dogs with brachycephaly. Brachycephalic or flat-faced breeds include the Pug, French Bulldog, Chow Chow, Boxer, English Bulldog, Shih Tzu, Lhasa Apso and Chihuahua.<\/span><\/p>\n

Coughing is a sign of BOAS, which often progresses to breathing difficulties, exercise intolerance, chronic snoring and gagging while eating. There are a few corrective surgeries to reduce the discomforts including coughing. However, it is not very common in India. (Tilley & Smith, 2015)<\/span><\/p>\n

Lifestyle adjustments and keeping your dog at a healthy bodyweight can help you reduce coughing in your dog.\u00a0<\/span><\/p>\n

Diagnosis: How will the vet know why my dog is coughing?<\/span><\/h2>\n

The veterinarian will conduct a thorough physical examination including checking the colour of your dog\u2019s gums, pulse rate, capillary refill time and pain response.\u00a0<\/span><\/p>\n

\"This<\/p>\n

In almost all cases, your veterinarian will recommend blood tests, biochemistry tests and\/or imaging tests to find the exact cause of your dog\u2019s coughing. (Tilley & Smith, 2015)<\/span><\/p>\n

The recommended tests will depend on the veterinarian\u2019s observation and your dog\u2019s health condition.\u00a0<\/span><\/p>\n

Since a dog\u2019s coughing can be a <\/span>sign of more than one illness<\/span><\/a> or disorder, your veterinarian will likely cover all grounds before giving a confirmed diagnosis.<\/span><\/p>\n

Treatment for coughing in dogs<\/span><\/h2>\n

\"This<\/p>\n

The treatment for coughing in dogs will depend upon the diagnosis. Different diseases and conditions will have different treatments.\u00a0<\/span><\/p>\n

Never try to medicate your dog on your own even if you think it\u2019s just an allergy or a minor infection. Human medication can have several unwanted side-effects, which may make your dog sicker. (AVMA, 2023).<\/span><\/p>\n
