Identifying the Symptoms of Heaves in Horses: What to Look Out For

Heaves, also known as recurrent airway obstruction (RAO), is a common respiratory condition found in horses. It is similar to asthma in humans and can significantly impact a horse’s health and performance. Early identification of heaves symptoms is crucial for timely treatment and management. In this section, we will discuss the key symptoms to look out for when suspecting heaves in horses.

1. Coughing

One of the primary symptoms of heaves in horses is persistent coughing. The cough may be dry or accompanied by the production of thick mucus. Initially, the cough may only occur during or after exercise, but as the condition progresses, it may become more frequent and persistent.

2. Labored Breathing

Horses with heaves often exhibit labored breathing, especially during physical exertion or in dusty environments. You may notice increased effort during inhalation and exhalation, with visible flaring of the nostrils and heaving movement of the abdomen. In severe cases, even normal breathing at rest may become difficult for the affected horse.

3. Wheezing

Wheezing is another common symptom of heaves in horses. It is characterized by a high-pitched whistling sound during breathing, resulting from the narrowing of airways and obstruction of airflow. The wheezing may be more pronounced during expiration.

4. Nasal Discharge

If a horse has heaves, you may notice the presence of nasal discharge. The discharge is usually thick, sticky, and may be yellowish or greenish in color. This is a result of the inflammation and excessive mucus production in the airways.

5. Exercise Intolerance

Horses with heaves may display reduced exercise tolerance. They may tire more quickly, show signs of fatigue, and have difficulty maintaining their usual performance levels. This is due to the compromised respiratory function and the reduced ability to deliver oxygen to the muscles.

6. Weight Loss

Chronic respiratory conditions like heaves can lead to weight loss in horses. The increased effort required for breathing and reduced appetite due to discomfort may result in a gradual decline in body condition. It is important to monitor the horse’s weight regularly and consult with a veterinarian if significant weight loss occurs.

7. Allergic Reactions

Heaves is often triggered or exacerbated by allergens such as dust, mold spores, and pollen. Horses with heaves may display allergic reactions, including skin itchiness, hives, and swelling. These reactions are a result of the immune system’s response to allergens and the release of inflammatory mediators.

In summary, recognizing the symptoms of heaves in horses is essential in ensuring early intervention and effective management of the condition. If you observe persistent coughing, labored breathing, wheezing, nasal discharge, exercise intolerance, weight loss, or allergic reactions in your horse, it is important to consult with a veterinarian for a proper diagnosis and treatment plan.
