Horses are magnificent creatures that have been a part of human history for centuries. They are known for their strength, agility, and beauty. However, like any living being, horses are prone to various health issues, one of which is heaves. Heaves, also known as recurrent airway obstruction (RAO), is a common respiratory problem in horses that can significantly impact their quality of life and performance.
What Causes Heaves in Horses?
Heaves is a chronic inflammatory condition that affects the small airways of the horse’s lungs. It is characterized by inflammation, scarring, and narrowing of the airways, which leads to coughing, wheezing, and difficulty breathing. The exact cause of heaves is not fully understood, but it is believed to be triggered by a combination of genetic and environmental factors.
Genetic Factors
Some breeds of horses, such as the Warmblood and the Thoroughbred, are more prone to developing heaves due to their genetic predisposition. Additionally, horses that have a family history of heaves are more likely to develop the condition.
Environmental Factors
Environmental factors, such as exposure to dust, mold, and other airborne pollutants, can also contribute to the development of heaves. Horses that are stabled or kept in areas with poor ventilation are more likely to develop the condition. Additionally, horses that are fed poor-quality hay or grain may be more susceptible to heaves.
Other Factors
Other factors that may contribute to the development of heaves include allergies, respiratory infections, and stress. Horses that are under stress, either physically or emotionally, may be more prone to developing heaves.
In conclusion, heaves is a complex condition that is caused by a combination of genetic and environmental factors. Understanding the causes of heaves is essential for developing effective treatment and prevention strategies. By identifying the underlying causes of heaves, horse owners and equine professionals can work together to improve the health and well-being of horses affected by this condition.
What Causes Heaves in Horses?
Heaves, also known as recurrent airway obstruction (RAO), is a common respiratory condition affecting horses worldwide. It is characterized by recurring episodes of coughing, wheezing, and labored breathing, often accompanied by a characteristic “heave” or “grunt” sound. Heaves can significantly impact a horse’s quality of life, making it difficult for them to perform daily activities and reducing their overall well-being.

What are the Causes of Heaves in Horses?
While the exact causes of heaves in horses are not fully understood, several factors are believed to contribute to the development of this condition. Some of the most common causes include:
- Environmental Factors: Exposure to pollutants, allergens, and irritants in the air can trigger or exacerbate heaves. These factors may include:
- Smoke and other airborne pollutants
- Mold and mildew
- Pollen and other allergens
- Genetic Predisposition: Some breeds, such as Warmbloods and Thoroughbreds, are more prone to developing heaves due to their genetic makeup.
- Age: Heaves can affect horses of all ages, but it is most common in older horses (over 10 years old).
- Lifestyle Factors: Horses that are stabled or kept in small, enclosed spaces may be more likely to develop heaves due to the lack of fresh air and increased exposure to pollutants.
- Underlying Medical Conditions: Certain medical conditions, such as chronic bronchitis or pneumonia, can increase a horse’s risk of developing heaves.
How Does Heaves Affect Horses?
Heaves can have a significant impact on a horse’s quality of life, causing a range of symptoms including:
- Coughing and wheezing
- Labored breathing
- Increased respiratory rate
- Difficulty performing daily activities
- Weight loss and decreased appetite
- Increased risk of secondary infections
Diagnosing Heaves in Horses
Diagnosing heaves in horses typically involves a combination of physical examination, radiography (x-rays), and bronchoscopy. The following tests may be performed:
- Physical Examination: A veterinarian will perform a thorough physical examination, including listening to the horse’s lungs with a stethoscope.
- Radiography (X-rays): X-rays can help identify any structural abnormalities in the lungs or airways.
- Bronchoscopy: A flexible tube with a camera and light on the end (bronchoscope) is inserted through the nose or mouth to visualize the airways and collect samples for further examination.
Treating Heaves in Horses
Treatment for heaves in horses typically involves a combination of medication, environmental changes, and lifestyle modifications. The following treatments may be recommended:
- Medications: Anti-inflammatory medications, bronchodilators, and corticosteroids may be prescribed to help reduce inflammation and open up the airways.
- Environmental Changes: Improving ventilation, reducing exposure to pollutants, and increasing the amount of fresh air in the horse’s environment can help alleviate symptoms.
- Lifestyle Modifications: Reducing the horse’s workload, providing regular exercise and stretching, and increasing the amount of time spent outdoors can help improve respiratory function.
- Air Purifiers: Installing air purifiers in the horse’s environment can help reduce exposure to pollutants and allergens.
Preventing Heaves in Horses
While it is not possible to completely prevent heaves in horses, there are several steps that can be taken to reduce the risk of developing this condition:
- Provide Adequate Ventilation: Ensure that the horse’s environment has good airflow and is well-ventilated.
- Reduce Exposure to Pollutants: Avoid exposing the horse to pollutants, allergens, and irritants in the air.
- Provide Regular Exercise: Regular exercise can help improve respiratory function and reduce the risk of developing heaves.
- Monitor the Horse’s Health: Regular veterinary check-ups can help identify any underlying medical conditions that may increase the risk of developing heaves.
Conclusion
Heaves is a common respiratory condition affecting horses worldwide. While the exact causes of heaves are not fully understood, several factors are believed to contribute to the development of this condition. By understanding the causes, symptoms, diagnosis, treatment, and prevention of heaves, horse owners can take steps to reduce the risk of developing this condition and improve the overall health and well-being of their horses.

Frequently Asked Questions
What are the common signs of heaves in horses?
Heaves, also known as recurrent airway obstruction, is a chronic respiratory disease that causes inflammation and constriction of the airways. Common signs of heaves in horses include coughing, wheezing, and labored breathing, especially after exercise or in dusty environments. Affected horses may also exhibit a lack of appetite, weight loss, and a general decline in overall health.
Is heaves more common in certain breeds of horses?
Yes, heaves is more common in certain breeds of horses, particularly those with a history of respiratory problems, such as draft horses, ponies, and miniature horses. However, any horse can develop heaves, regardless of breed or age, if they are exposed to environmental allergens or irritants.
What are the most common triggers of heaves in horses?
The most common triggers of heaves in horses include exposure to dust, mold, and other environmental allergens. Hay and grain can also be triggers, especially if they are contaminated with mold or dust. Additionally, some horses may develop heaves in response to changes in their environment, such as moving to a new barn or being exposed to new horses.
Can heaves be prevented in horses?
While it is not possible to completely prevent heaves in horses, there are steps that can be taken to reduce the risk of developing the disease. These include providing a clean and dust-free environment, using HEPA filters to remove allergens from the air, and avoiding exposure to known triggers. Regular veterinary care and monitoring can also help identify early signs of heaves and prevent the disease from progressing.
How is heaves typically treated in horses?
Heaves is typically treated with a combination of medications and lifestyle changes. Medications may include bronchodilators, corticosteroids, and antihistamines, which help to reduce inflammation and open up the airways. Lifestyle changes may include providing a clean and dust-free environment, avoiding exposure to known triggers, and using oxygen therapy to help horses breathe more easily. In severe cases, surgery may be necessary to remove damaged lung tissue or to improve airflow in the lungs.
