Horses with chronic respiratory problems are now encountered in almost every stable. Most horse owners now know that the problem is also widespread among recreational horses. But how do I recognize that my horse has a respiratory problem? And what should I do if I do so?
1. Cough
"A little cough when trotting is normal." – Not at all! The urge to cough is much harder to trigger in horses than in humans. A healthy horse doesn't cough even when trotting. Therefore, even a slight cough should be examined and, if necessary, examined by a veterinarian.
2. Nasal discharge
Some horses have nasal discharge, especially after exercise. A little clear nasal discharge is perfectly normal. However, if the amount increases significantly, or if the nasal discharge becomes milky or yellowish or green , caution is advised. In this case, you should also consult your vet. We also recommend taking a close look if the nasal discharge is on one side of the horse. Problems with the teeth or sinuses could be the cause. Important: A horse with respiratory problems does not necessarily have nasal discharge! Some horses simply swallow the mucus, so we do not necessarily see it.
3. Performance deficit
Again, not all horses with respiratory problems cough. Some horses with lung problems are only noticeable due to reduced performance. Certain movements are difficult, or the final jumps in the course don't go as planned. The horse tires significantly more quickly than usual. Respiratory problems can lead to a reduced oxygen supply for various reasons, which in turn can lead to a loss of performance.
4. Respiratory rate
A healthy horse takes approximately 8-16 breaths per minute at rest . This rate increases during exercise. If the breathing rate is higher at rest, or if it takes a long time to return to normal after exercise, this could be an indication of a respiratory problem. The way the horse breathes should also be observed. Horses with respiratory problems often exhibit what is known as "belly breathing." It is more difficult for the horses to exhale the inhaled air. Therefore, these horses "push" with their abdominal muscles.
What do I do if I notice something unusual about my horse?
If I notice any of the symptoms listed above in my horse, I should consult a veterinarian if in doubt. Of course, a respiratory illness could also be a simple infection. If such a condition is suspected, the horse's temperature should also be taken to determine the current state of the condition. However, most horses presented to the veterinarian with respiratory illnesses are horses with chronic conditions. To prevent this from happening, we should always keep a close eye on our horses.
