Does your horse cough when you ride it?
Did you know that your horse can have issues with both the upper respiratory anatomy and the lower respiratory airway that causes poor performance?
The only way to truly separate some of these issues is by the use of an endoscope examination. Which means we can visually check the upper respiratory anatomy is correct, that the anatomy of the airway that operates the opening and closing of the trachea is normal and that the trachea itself is clear of mucus. In some cases the referral for a dynamic endoscopy helps diagnosis for upper respiratory issues such as dorsal displacement of the soft palate, this can occur in racehorses and also in horses during exercise that involves flexion at the poll.
The trachea is the windpipe into the lung tissue itself and should be free of mucus and or blood. When checking a coughing horse we often take a washed sample from the trachea for culture and a washed sample from the lungs (BAL) for inflammatory cells. Why? Because this is the most diagnostic information to tell us your horse may have asthma or a alternatively a bacterial infection.
Equine asthma is one of the most diagnosed issues of the horse with clinical signs such as coughing, clear nasal discharge, shortness of breath and poor performance (understandably). If your horse is making a noise while working or coughing when you ride it, get in touch today, as left untreated it can create chronic pulmonary issues commonly seen as 'heaves' later in life.
