Introduction
Breaking a horse's wind, often referred to as "heaves" or "recurrent airway obstruction (RAO)", is a chronic respiratory condition that affects horses. This condition is similar to asthma in humans and is characterized by difficulty in breathing, chronic coughing, and reduced exercise tolerance. Understanding the causes, symptoms, and management of this condition is crucial for horse owners to ensure the well-being of their animals.
Understanding Equine Respiratory Health
Horses, like humans, rely heavily on their respiratory systems for overall health and performance. A horse's respiratory system is designed to handle large volumes of air, but when compromised, it can lead to severe health issues. Respiratory conditions can significantly impact a horse's quality of life and its ability to perform. Therefore, recognizing and addressing these issues early is vital.
What Does 'Breaking a Horse's Wind' Mean?
The term "breaking a horse's wind" dates back to a time when understanding of equine health was less advanced. Today, we know that this condition is a serious respiratory ailment that requires proper management. RAO, or heaves, is a chronic condition that can be managed but not cured.
Causes of Heaves
Heaves is primarily caused by an allergic reaction to inhaled environmental allergens such as dust, mould, and other irritants commonly found in hay, straw, and bedding. Prolonged exposure to these allergens triggers an inflammatory response in the horse's airways, leading to bronchoconstriction (narrowing of the airways), mucus production, and bronchospasm (tightening of the muscles around the airways). For more details on managing allergens, check out our stable rugs collection.
Symptoms of Heaves
The symptoms of heaves can vary in severity and may include:
- Chronic coughing, especially during or after exercise or while eating
- Increased respiratory effort and dyspnea (difficulty breathing)
- Nasal discharge
- Exercise intolerance
- Wheezing and abnormal lung sounds
- Weight loss and poor body condition
- Visible "heave line" on the ventral abdomen due to hypertrophy of the abdominal muscles used for breathing
Diagnosing Heaves
Diagnosing heaves involves a thorough clinical examination by a veterinarian, including listening to the horse's chest with a stethoscope to detect abnormal lung sounds. In some cases, a rebreathing bag may be used to intensify the horse's respiratory effort for better auscultation. Additional diagnostic tests such as bronchoalveolar lavage (BAL) may be performed to analyse the cells and mucus in the lower airways. For more on diagnostic tools, refer to MSD Veterinary Manual.
Management and Treatment
Heaves is a chronic condition that cannot be cured but can be managed effectively through environmental control and medical treatment. Key management strategies include:
Environmental Control
Reducing exposure to dust and mould by soaking hay, using dust-free bedding, and ensuring good ventilation in stables. Feeding hay from the ground rather than in a hay net can also help mucus drain from the lungs. For dust-free bedding options, visit our jodhpur collection.
Medication
Bronchodilators and corticosteroids are commonly used to reduce airway inflammation and improve breathing. These can be administered orally, intravenously, or through inhalation. Consult with your veterinarian for the best treatment plan for your horse.
Nutritional Support
Supplements that support the immune system and respiratory health can be beneficial in managing symptoms. Explore our range of everyday horse vitamins & supplements for options that can help maintain your horse's health.
Prevention
Preventing heaves involves minimizing the horse's exposure to environmental allergens. This includes:
- Using low-dust bedding materials
- Feeding high-quality, dust-free hay or haylage
- Ensuring proper ventilation in stables
- Regularly cleaning and maintaining the horse's living environment to reduce mould and dust accumulation
Conclusion
Breaking a horse's wind, or heaves, is a significant respiratory condition that requires diligent management to ensure the horse's quality of life. By understanding the causes, symptoms, and management strategies, horse owners can take proactive steps to prevent and alleviate the effects of this chronic condition. Always consult with a veterinarian for a proper diagnosis and tailored treatment plan for your horse. For more detailed information on managing heaves in horses, you can refer to resources such as the MSD Veterinary Manual and the University of Florida Large Animal Hospital.

Asked By You
How do you treat broken wind in horses?
Treating broken wind, or heaves, in horses involves a combination of environmental management and medical treatments. Reducing the horse's exposure to dust, mould, and other allergens is crucial. This can be achieved by using dust-free bedding, soaking hay, and ensuring good ventilation in stables. Medications such as bronchodilators and corticosteroids are also commonly used to reduce inflammation and improve breathing.
What does a wind operation do to a horse?
A wind operation, also known as a tie-back surgery, is a procedure performed to improve a horse's breathing by addressing issues related to the larynx or vocal cords. This surgery is often done on racehorses or performance horses that suffer from conditions like laryngeal hemiplegia, where the larynx partially collapses, causing breathing difficulties. The surgery involves tying back one of the vocal cords to keep the airway open during strenuous activity.
What is involved in breaking a horse?
Breaking a horse, also known as starting a horse, involves training a young horse to accept a rider and respond to basic commands. This process includes handling the horse regularly, introducing it to a saddle and bridle, and gradually teaching it to carry a rider. The training focuses on building trust and communication between the horse and the trainer, ensuring the horse is calm and responsive.
What is it called when a horse blows air?
When a horse blows air forcefully through its nostrils, it is often referred to as "snorting" or "blowing." This behaviour can indicate excitement, curiosity, or clearing of the nasal passages. Snorting is a common sound that horses make and is usually not a cause for concern unless accompanied by other symptoms of respiratory distress.
