What are the most common causes of dog cough?

Have you noticed that your dog is coughing more than usual? Here's everything you need to know about the most common causes of dog cough.

Why dogs cough

Dogs often cough to clear their throat, especially if they've accidentally swallowed some dust or came into contact with germs or any particles. 

If your dog coughs occasionally, there's nothing to worry about. However, if their cough becomes repetitive and comes with changes in breathing sounds, it can be a symptom of a more serious issue.

Types of dog cough

Being able to describe your dog's cough will not only help you identify the seriousness of the situation but also help the vet narrow down the potential causes. 

Try asking yourself the following questions: Is it a deep and dry cough or is it more wet and phlegmy? Is it a gagging cough? Does it also happen when your dog sleeps? 

You can also record your dog's cough so that the vet can hear it.

Most Common Causes of Dog Cough

Kennel Cough

A deep and dry cough could be a symptom of kennel cough, which is highly contagious and can be picked up in any environment where several dogs are together, such as dog care facilities.

In most cases, it's nothing serious but it can sometimes damage the lungs.


Sore Throat

A gagging cough can indicate an upper airway infection or blockage. If an object is stuck in your dog's throat, preventing them from swallowing and breathing properly, they need immediate care.

Lung Problems

A wet and phlegmy cough is often a symptom of a pulmonary issue, especially if your dog seems to have troubles breathing. 

Your dog needs to be seen by the vet immediately as they might have pneumonia. This illness can be caused by bacteria, viruses or parasites and affects dogs with a weaker immune system such as puppies and senior dogs.


Heart Disease

Dogs can suffer from several types of heart disease. When fluid accumulates in the lungs and causes coughing (especially when sleeping or lying down), it is most likely a congestive heart failure.

Some breeds are more prone to heart disease than others, such as Cavalier King Charles. It's important to take them to the vet rapidly to start the appropriate treatment.Treating Dog Cough


Treating dog cough

Many causes are treatable but the sooner the issue is identified, the better, especially if their cough is a symptom of a life-threatening disease.

If you notice any change in your dog's cough, whether it's the type or frequency, it's always best to have them seen by their vet.
