Horse coughing is a common problem that can be caused by a variety of factors including allergies, respiratory infections, and environmental factors. A horse’s cough can range from mild to severe, and in some cases, it can be a sign of a more serious health issue.

Fortunately, there are several remedies available to help alleviate a horse’s cough. Some of these remedies include changes in the horse’s diet, environmental modifications, and medications. It is important to consult with a veterinarian before administering any medication to a horse, as some medications may have adverse effects on a horse’s health.
In this article, we will explore some of the most effective horse coughing remedies. We will discuss the causes of horse coughing, as well as the various treatment options available. By the end of this article, readers will have a better understanding of how to identify and treat horse coughing, ensuring their horse’s health and well-being.
Understanding Horse Coughing
Coughing is a natural reflex that helps to clear the airways of mucus, dust, and other irritants. However, persistent coughing can be a sign of a more serious underlying condition.
There are several different types of cough that can affect horses, including dry cough, wet cough, and honking cough. A dry cough is typically caused by irritation of the upper airways, while a wet cough is usually a sign of inflammation or infection in the lower airways. Honking cough is a deep, harsh cough that is often associated with respiratory allergies or other underlying conditions.
Persistent coughing can be a sign of a range of respiratory conditions, including equine asthma, pneumonia, and heaves. It is important to identify the underlying cause of the cough in order to provide appropriate treatment and prevent further complications.
There are several steps that horse owners can take to help prevent coughing in their horses. These include ensuring that the horse is housed in a clean, well-ventilated environment, providing plenty of fresh water and high-quality feed, and minimizing exposure to dust and other irritants. Regular veterinary check-ups can also help to identify and treat any underlying respiratory conditions before they become more serious.
Causes of Horse Coughing
Horses can develop a cough for a variety of reasons. Understanding the underlying causes of coughing in horses is important to determine the appropriate treatment. Some of the common causes of horse cough include infections and diseases, environmental factors, and other causes.
Infections and Diseases
Infections and diseases are a common cause of horse cough. Some of the most common infections and diseases that can cause coughing in horses include:
- Equine influenza
- Strangles
- Pneumonia
- Rhinopneumonitis
- Infectious respiratory disease
In addition to these infections, horses can also develop coughs due to viral and fungal infections.
Environmental Factors
Environmental factors can also play a role in causing coughing in horses. Exposure to dust, mold, and other irritants in the environment can cause horses to cough. Poor ventilation and changes in the environment and bedding materials such as straw and sawdust can also be contributing factors.

Other Causes
In addition to infections and environmental factors, there are other causes of horse cough. Allergies, parasites, and lungworm can all cause coughing in horses. Choke, cleft palate, and upper airway issues can also lead to coughing. Guttural pouches, which are air-filled sacs in the horse’s head, can also become infected and cause coughing.
It is important to identify the underlying cause of the horse’s cough to determine the appropriate treatment. A veterinarian can help diagnose the cause of the cough and recommend the appropriate treatment options.
Symptoms and Diagnosis
Horses can develop coughs due to a variety of reasons, including infections, allergies, irritants, or underlying respiratory conditions. It is important to recognize the symptoms of a cough in a horse and seek veterinary care promptly.
Recognizing Symptoms
It’s important to keep an eye out for the following symptoms that may indicate a cough:
- Nasal discharge
- Lethargy
- Mucous
- Wheezing
- Increased respiratory rate
- Weight loss
- Loss of appetite
- Runny nose
If a horse exhibits any of these symptoms, it is important to contact a veterinarian for further investigation.
Diagnosis Methods
A veterinarian may use a combination of diagnostic tools to determine the cause of a horse’s cough. These may include:
- Listening to the horse’s lungs and airways with a stethoscope
- Performing blood work to check for signs of infection or inflammation
- Collecting nasal swabs to test for bacterial or viral infections
- Using ultrasound or endoscopy to visually examine the respiratory system
By using these diagnostic methods, a veterinarian can determine the underlying cause of a horse’s cough and develop an appropriate treatment plan.

Horse Coughing Remedies – Treatment and Prevention
Horse coughing can be treated and prevented by a variety of methods, including medical treatments, preventive measures, and nutritional supplements.
Medical Treatments
If a horse is experiencing coughing due to an infection, antibiotics may be prescribed by a veterinarian. Bronchodilators can also be used to help open up the airways and make breathing easier. Anti-inflammatories like Banamine can be used to reduce inflammation in the airways and alleviate coughing.
Preventive Measures
Vaccination against respiratory diseases is an important step in preventing coughing. Resting horses after transport or exercise can also help prevent coughing. Horse owners can also reduce exposure to dust and other irritants by using dust-free wood shavings for bedding.
Nutritional Supplements
Nutritional supplements can be used to support respiratory health and reduce the risk of coughing. Supplements like pelleted hay and hay cubes can reduce the amount of dust and mold in a horse’s diet. Omega-3 fatty acid supplements can also help support respiratory health.
Specific Conditions
Recurrent Airway Obstruction
Recurrent Airway Obstruction (RAO), also known as Heaves or Chronic Obstructive Pulmonary Disease (COPD), is a common respiratory condition in horses. It is characterized by bronchoconstriction, inflammation, and mucus accumulation in the airways. The condition is often caused by exposure to allergens such as dust, mold, and hay.
To manage RAO, it is important to reduce exposure to allergens. This can be done by providing good ventilation in the barn, using dust-free bedding, and feeding low-dust hay. Medications such as bronchodilators and corticosteroids can also be used to manage symptoms.
Exercise-Induced Pulmonary Hemorrhage
Exercise-Induced Pulmonary Hemorrhage (EIPH) is a condition in which horses experience bleeding in the lungs during exercise. It is most commonly seen in racehorses and can be caused by the high-intensity exercise that they undergo.
To manage EIPH, it is important to provide adequate rest and recovery time between races. Medications such as furosemide can also be used to reduce the severity of bleeding.
Respiratory Issues in Foals
Respiratory issues are also common in foals, particularly those that are born prematurely or have weak immune systems. These issues can include pneumonia, bronchitis, and other respiratory infections.
To manage respiratory issues in foals, it is important to provide good nutrition and a clean environment. Medications such as antibiotics and bronchodilators can also be used to manage symptoms.
