It is important not to confuse dry coughs, wet coughs and sinusitis in horses In a wet or productive cough , there is mucus secretion in the airways. Dust : in a box stall, dust is more common and depends on the straw or wood shavings used or the way the stables operate. Mould : the presence of mould depends on the choice of concentrates and hay.

Preventing emphysema and chronic diseases Preventing the development of these diseases in horses as far as possible is thus absolutely essential. Here is what our experts advise: Provide horses with good-quality hay and feed in general to prevent exposure to dust and moulds. For stabled horses, pay careful attention to straw quality. Sometimes disease is present, but the condition is not yet advanced enough for abnormal lung sounds to be detected with a stethoscope.

A thoracic ultrasound allows veterinarians to visualize the lungs and diagnosis a consolidation deflated lung that is no longer able to participate in oxygen exchange , fluid in the lungs, or other problems.

If there is fluid in the chest pleural effusion , ultrasound helps determine the most accurate location for thoracocentesis collection of lung fluid for analysis , which will in turn provide more information. An endoscopy is another useful tool for evaluating a horse with a cough. An endoscopy sends a tiny camera into the trachea, upper airways, and guttural pouches so the veterinarian can see what is happening.

Tracheal collapse and partial obstruction of the trachea by a foreign body or a mass can be visualized via endoscopy. Conditions of the upper airway that can cause a cough include anatomic defects that result in the airway not being appropriately protected from debris, such as dorsal displacement of the soft palate, rostral placement of the palatopharyngeal arch, arytenoepiglottic fold entrapment, and subepiglottic cysts. The guttural pouches can be inspected for conditions such as empyema pus in the guttural pouches , chondroids small masses formed by hardened pus , and fungal infection.

If nasal discharge is present with a cough, skull radiographs X-rays may be warranted. With an infected sinus, discharge may travel not only out the nose, but also down the throat, causing a cough. If the cough occurs only during or after exercise, it is possible your horse has exercise-induced pulmonary hemorrhage. In these cases, the blood sometimes runs down the throat and causes a cough.

If the cough occurs only when your horse eats, conditions such as a cleft palate, dorsal displacement of the soft palate, and soft palate paresis should be ruled out. RAO is a condition that generally affects older horses. These horses show increased respiratory effort at rest, exercise intolerance, and a cough. It is frequently caused by an allergy, most often mold or dust. IAD is a condition that generally affects younger horses. Signs also include exercise intolerance and a cough, but IAD horses do not have increased respiratory effort at rest.
