Equine Asthma (Heaves / COPD) in horses, also known as equine asthma syndrome, is a chronic respiratory condition characterized by airway inflammation, coughing, and difficulty breathing.

Definition of Equine Asthma

Equine asthma is a non-infectious inflammatory airway disease. It has previously been called Recurrent Airway Disease (RAO) or sometimes called Chronic Obstructive Pulmonary Disease (COPD). Equine asthma is an allergic reaction that can be triggered by environmental allergens such as fungal spores found in hay and straw. This reaction leads to the production of excess fluid and thickening of the small airways, causing them to become obstructed.
As a result, the horse must make an increased effort to breathe and may develop a cough to clear trapped mucus.
 
While there is no cure for this progressive condition, it can be managed through various steps to help the horse cope with it.

Treatment of Equine Asthma

Many cases can be effectively managed through changes in the horse’s environment and management, including removing the cause of the allergy and implementing a “dust free” management system with clean, non-organic bedding and dampened feed.
Severe or chronic cases may require medication, such as injectable or inhaled steroids, bronchodilators, or Atropine.
It is important to maintain a clean, dust-free environment and practice good management in conjunction with any drug treatment to effectively manage this condition.

Prevention of Asthma in Horses

There are several measures that can be taken to help prevent equine asthma:

Implement a “dust-free” management system: This involves minimizing the amount of dust in the horse’s environment, such as using non-organic bedding, soaking hay before feeding, and dampening dry feed.

Maintain good ventilation: Proper ventilation can help reduce the concentration of allergens in the air.

Practice good hygiene: Keeping the horse’s living area clean and free of excess dust and dirt can help prevent the development of asthma.

Store hay and straw properly: Storing hay and straw in a dry, well-ventilated area can help reduce the amount of dust and spores in the air.

Avoid exposing the horse to high levels of allergens: If the horse is sensitive to certain allergens, such as pollen, it may be necessary to move them to a low-pollen area during high pollen counts.

Work with a veterinarian: A veterinarian can help identify potential allergens and develop a management plan to help prevent the development of asthma.
