You notice your dog sitting quietly, and all of a sudden it starts coughing. A sharp little sound, which can be wet as well as dry.

This makes you wonder, why is my dog coughing? It is normal for dogs to cough sometimes. They cough to clear their throat or lungs, but when it happens too often, it can mean something is wrong.

Understanding the different dog coughing causes is essential for you as a dog owner because it helps you to understand what requires extra care and what does not.

In this blog, you will learn everything about dog coughing and find out the reasons that cause it.

Why Is My Dog Coughing?

A dog cough is a signal that their body is trying to do something. Sometimes it is clearing dust, smoke, or pollen. At times, it can be the lungs or heart telling you that something is wrong.

Dogs cough in different ways, like a small barky cough, a honk, or a wet hacking sound. Sometimes it comes with gagging, and sometimes it happens only when the dog gets excited or pulls on the leash.

If a dog coughs a lot, more than a couple of days, or the cough seems strong, it should not be ignored. If coughing comes with tiredness, loss of appetite, or trouble breathing, it is time to check with a vet.

Common Dog Coughing Causes

Coughing can be caused by various reasons, and you can find the most common reasons in the following list:

Infections

Dogs get viruses and bacteria, because of which kennel cough is the most common. Dogs can easily pass it to each other.

Allergies

Dust, smoke, pollen, or grass allergies can irritate the throat or lungs, which can trigger coughing.

Heart Disease

Some heart problems cause fluid in the lungs. This makes dogs cough often, especially at night or when resting.

Trachea Issues

Smaller dogs may have a trachea that collapses, which makes a honking cough sound.

Parasites

Worms in the lungs or heart can lead to coughing and breathing difficulty.

Foreign Objects

Dogs sometimes inhale seeds, food, or toys. If something gets stuck, coughing starts suddenly.

Understanding Dog Coughing and Gagging

Some dogs cough and gag together. Gagging can happen if mucus, food, or fluid irritates the throat. Pneumonia or reflux can also cause this. In reflux, stomach contents irritate the esophagus.

Dog coughing and gagging may look like choking, but it is different. If it happens repeatedly, it could be a serious problem. Blockages, aspiration pneumonia, or infections might be the cause. Repeated gagging should be checked by a vet.

What is Dog Reverse Coughing and Sneezing?

Dog reverse coughing and sneezing is a different kind of sound. It happens when the dog pulls air quickly into the throat. Not pushed out, pulled in. It looks alarming but often is harmless.

Dogs may do it when excited, when the leash pulls on their neck, or when air changes temperature suddenly. But if it happens frequently, it can indicate allergies, nasal irritation, or an airway problem. Most of the time, it is not dangerous.

Dog Coughing Treatment Options

Dog Coughing Treatment

Treatment depends on the cause. Some common ways to treat dog coughing include:
