What is Cough?

Coughing is a common reflex action that helps to clear the throat, airways, or lungs of irritants, foreign bodies, mucus, or pathogens. Coughing in pets can be an occasional, harmless reaction or a sign of a more severe health issue.

Understanding the Basics

Coughing occurs when the respiratory tract is irritated or inflamed. The respiratory system includes the nose, throat, windpipe (trachea), and lungs. When something irritates these areas, the body responds with a cough to try to expel the offending substance.

Types of Cough

  1. Dry Cough: This cough sounds harsh and doesn't produce mucus. It's often a sign of irritation or inflammation in the throat or upper airways. Common causes include kennel cough in dogs or a viral upper respiratory infection in cats.
  1. Wet Cough: This cough is accompanied by the sound of mucus or phlegm moving in the airways. It might indicate the presence of fluid in the lungs or airways, which can be due to infections like pneumonia or chronic bronchitis.
  1. Hacking Cough: This persistent, forceful cough can sound like gagging or retching and might be a sign of a more serious condition, such as tracheal collapse or severe respiratory infection.
  1. Honking Cough: This sounds like a goose honk and is typically associated with tracheal collapse, especially in small dog breeds.

Recognizing When Coughing is a Problem

While an occasional cough may not be a cause for concern, frequent or severe coughing warrants a closer look. Persistent coughing can indicate underlying health issues that require veterinary attention. Here are some signs that the cough might be severe:

  • Duration: If your pet's cough lasts more than a few days, consult a vet.
  • Severity: Strong, forceful coughing that disrupts your pet's usual activities or sleep needs to be addressed.
  • Accompanying Symptoms: Symptoms like difficulty breathing, lethargy, weight loss, nasal discharge, or coughing up blood are red flags.

Understanding the nature of your pet’s cough and recognizing when it’s more than just a simple reflex can help you seek timely veterinary care and ensure your pet stays healthy and comfortable.

Common Causes of Cough in Pets

Coughing in cats and dogs can be caused by various factors. Understanding these causes can help pet owners identify potential issues early and seek appropriate treatment.

  • Infectious Causes


Kennel Cough (Canine Infectious Tracheobronchitis)

This is a highly contagious respiratory infection in dogs. It's often caused by a combination of bacteria and viruses, such as Bordetella bronchiseptica and canine parainfluenza virus. Symptoms include a dry, hacking cough, sometimes accompanied by nasal discharge and sneezing.

Feline Upper Respiratory Infection

Similar to a cold in humans, this infection is common in cats and can be caused by viruses like feline herpesvirus or calicivirus. Symptoms include sneezing, nasal congestion, eye discharge, and coughing due to irritation in the throat and airways.


Pneumonia is an infection of the lungs, common in both cats and dogs, that can be caused by bacteria, viruses, or fungi. It results in a wet cough, fever, difficulty breathing, and lethargy.

  • Non-Infectious Causes



Pets can be allergic to environmental factors such as pollen, dust, mold, or certain foods. Allergies can cause coughing due to inflammation and irritation in the airways.

Heart Disease

Conditions like congestive heart failure can lead to fluid buildup in the lungs, causing a persistent cough. This is often seen in older dogs or certain breeds predisposed to heart conditions.

Tracheal Collapse

This condition is common in small dog breeds like Yorkies and Pomeranians. The trachea, or windpipe, collapses, causing a honking cough, especially during excitement or exercise.


Feline asthma is a chronic condition where the airways become inflamed and narrow, leading to coughing, wheezing, and difficulty breathing. Triggers can include allergens, smoke, or stress.

  • Environmental Factors



Exposure to smoke, strong odors, dust, or chemicals can irritate the respiratory tract, leading to coughing. Keeping the living environment clean and free from harsh irritants can help reduce this risk.

Foreign Bodies

Objects like grass, seeds, or small toys can accidentally be inhaled or swallowed, getting lodged in the throat or airways. This can cause sudden, severe coughing as the body attempts to expel the object.

Temperature and Humidity

Extreme temperatures or very dry air can irritate the respiratory system, leading to coughing. Using humidifiers and maintaining a comfortable living environment can help.

Recognizing these common causes of coughing can help you understand what might be affecting your pet. If you notice persistent or severe coughing, it's important to consult a veterinarian to determine the underlying cause and appropriate treatment.

When to Seek Veterinary Care

A persistent cough in your pet that lasts for more than a few days or shows no signs of improvement should be a cause for concern. It's important to monitor the duration and consistency of the cough to determine if it requires veterinary attention.

If your pet's cough is severe, characterized by its intensity, frequency, or if it prevents your pet from eating, sleeping, or playing normally, immediate veterinary consultation is advisable. 

When the cough is accompanied by other symptoms, such as those previously listed, it becomes even more crucial to seek veterinary help. The presence of additional symptoms may indicate a more serious underlying condition that needs prompt medical attention.

Noticeable changes in your pet's behavior, such as unusual lethargy, depression, or any significant behavioral changes, should also prompt a visit to the veterinarian. Behavioral changes can be indicative of illness or distress, and addressing them early can prevent further complications.

Paying close attention to these symptoms can help you identify when your pet's cough is more than a minor irritation. Early detection and treatment ensure your pet remains healthy and comfortable.

Conventional Treatment Options for Cough in Pets

When it comes to treating coughs in cats and dogs, veterinarians use a variety of effective methods to ease symptoms and tackle the root causes.

First, antibiotics are often prescribed to combat bacterial infections like kennel cough or pneumonia. These medications work to eliminate the bacteria responsible for the infection, providing relief to your pet.

Anti-inflammatory drugs are also commonly prescribed. These medications are particularly useful in reducing inflammation within the respiratory tract. By doing so, they help lessen the coughing and discomfort your pet might be experiencing.

For persistent, non-productive coughs, veterinarians may recommend cough suppressants. These are designed to control continuous coughing, allowing your pet to rest and recover more comfortably. If your pet is struggling with asthma, bronchodilators can be extremely helpful. These medications work by opening up the airways, making it easier for your pet to breathe.

Diuretics are sometimes administered to reduce fluid buildup in the lungs. This is especially beneficial for pets dealing with heart disease, as it helps alleviate some of the associated respiratory issues.
